Macs are $535 less expensive than PCs
“In 2015, IBM let their employees decide – Windows or Mac. “The goal was to deliver a great employee choice program and strive to achieve the best Mac program,” Previn said. An emerging favorite meant the deployment of 30,000 Macs over the course of the year. But that number has grown. With more employees choosing Mac than ever before, the company now has 90,000 deployed (with only five admins supporting them), making it the largest Mac deployment on earth.”
“But isn’t it expensive, and doesn’t it overload IT? No. IBM found that not only do PCs drive twice the amount of support calls, they’re also three times more expensive. That’s right, depending on the model, IBM is saving anywhere from $273 – $543 per Mac compared to a PC, over a four-year lifespan. “And this reflects the best pricing we’ve ever gotten from Microsoft,” Previn said. Multiply that number by the 100,000+ Macs IBM expects to have deployed by the end of the year, and we’re talking some serious savings.”
Deepgram finds speech with A.I.
“Searching through recordings is really difficult. In terms of workflow, usually the raw audio is transcribed into text, which is then fed into a search tool. If you transcribe using human transcription, it’s too time consuming and expensive. If you try to do it with automatic speech-to-text then search accuracy is the problem. […] Deepgram is an artificial intelligence tool that makes searching for keywords in speeches, private conversations and phone calls faster, cheaper and easier than the old way of doing things. Deepgram indexes audio files in more than half the time of a human transcriber, and costs only 75¢ per hour of audio.”
Amazing. Try it for yourself and see if it doesn’t blow your panties off.
Time Travel: A History by James Gleick
“From the acclaimed author of The Information and Chaos, here is a mind-bending exploration of time travel: its subversive origins, its evolution in literature and science, and its influence on understanding time itself.”
Sleeping into the future is what we do every night.
“Man can do what he will, but he cannot will what he wills.” — Arthur Schopenhauer
“People living in different countries kill each other at irregular time intervals, so that also for this reason anyone who thinks about the future must live in fear and terror. I trust that posterity will read these statements with a feeling of proud and justified superiority.” — Albert Einstein’s message in the time capsule buried at the 1939 New York World’s Fair
We know that complete certainty must always elude us. We know that for certain.
“Time and space are modes by which we think, and not conditions in which we live.” — Albert Einstein
“I have approximate answers and possible beliefs and different degrees of certainty about different things, but I am not absolutely sure of anything.” — Richard Feynman
What is time? Things change, and time is how we keep track.
Schopenhauer asserted that life and dreams are pages from the same book. To read them in their proper order is to live, but to browse among them is to dream.
No one can really explain how memories are formed and retrieved. Nor can anyone explain away Proust’s paradoxical contention: that the past cannot truly be recovered by searching our memories, by interrogating them, by rewinding the film or reaching back into the drawer; rather, that the essence of the past, when it comes to us at all,comes unbidden.
If you ever see yourself coming out of a time machine, run the other way as fast as you can. Nothing good can come from meeting yourself. — Charles Yu
We experience childhood one way when we’re living it and another way when we relive it in memory.
But if memory is the action of recollection, the act of remembrance, then it implies an ability to hold in the mind two constructs, one representing the present and another representing the past, and to compare them, one against the other. How did we learn to distinguish memory from experience?
Our conscious brains invent the concept of time over and over again, inferring it from memory and extrapolating from change. And time is indispensable to our awareness of self. […] You order the slices of your life. You edit the film even as it records.
“There were buttons and switches everywhere—buttons to call for food, for music, for clothing. There was the hot-bath button, by pressure of which a basin of (imitation) marble rose out of the floor, filled to the brim with a warm deodorized liquid. There was the cold-bath button. There was the button that produced literature, and there were of course the buttons by which she communicated with her friends. The room, though it contained nothing, was in touch with all that she cared for in the world.” — The Machine Stops by E. M. Forster
Why do we need time travel, when we already travel through space so far and fast? For history. For mystery. For nostalgia. For hope. To examine our potential and explore our memories. To counter regret for the life we lived, the only life, one dimension, beginning to end.
“We know it all now, with our thoughts travelling at the speed of tweet. We are time travelers into our own future. We are Time Lords.” — Ali Smith
If we confuse the real world with our many virtual worlds, it’s because so much of the real world is virtual.
Time’s winged chariot isn’t taking us anywhere good. […] The past, in which we did not exist, is bearable, but the future, in which we will not exist, troubles us more.
“We perceive time only because we know we have to die.” — Heidegger
Time Travel: A History (review)
Maria Popova describes James Gleick’s new book Time Travel: A History, “a dizzying tour of science, philosophy, and their interaction with literature.” A few snippets from her lengthy review:
“Why do we need time travel, when we already travel through space so far and fast? For history. For mystery. For nostalgia. For hope. To examine our potential and explore our memories. To counter regret for the life we lived, the only life, one dimension, beginning to end.”
“Things have been, says the legal mind, and so we are here. The creative mind says we are here because things have yet to be.”
“The mind is what we experience most immediately and what does the experiencing.”
“If we have only the one universe — if the universe is all there is — then time murders possibility. It erases the lives we might have had.”
One of my favorite topics by one of my favorite writers.
UPDATE: From a good piece in The Guardian: “Howard and his editors also manage a number of celebrity Beatle-fan coups, like the day when, to their astonishment, they spotted a 14-year-old Sigourney Weaver looming lankily over her fellow teenyboppers in footage of a 1964 show.”
A new mind for an old species
“Technology and life must share some fundamental essence. … However you define life, its essence does not reside in material forms like DNA, tissue, or flesh, but in the intangible organization of the energy and information contained in those material forms. Both life and technology seem to be based on immaterial flows of information.” (What Technology Wants, Kevin Kelly)
“Humanity is developing a sort of global eyesight as millions of video cameras on satellites, desktops, and street corners are connected to the Internet. In your lifetime it will be possible to see almost anything on the planet from any computer. And society’s intelligence is merging over the Internet, creating, in effect, a global mind that can do vastly more than any individual mind. Eventually everything that is known by one person will be available to all. A decision can be made by the collective mind of humanity and instantly communicated to the body of society.” (God’s Debris, Scott Adams, 2004)
“All information will come in by super-realistic television and other electronic devices as yet in the planning stage or barely imagined. In one way this will enable the individual to extend himself anywhere without moving his body— even to distant regions of space. But this will be a new kind of individual— an individual with a colossal external nervous system reaching out and out into infinity. And this electronic nervous system will be so interconnected that all individuals plugged in will tend to share the same thoughts, the same feelings, and the same experiences. […] If all this ends with the human race leaving no more trace of itself in the universe than a system of electronic patterns, why should that trouble us? For that is exactly what we are now!” (The Book: On the Taboo Against Knowing Who You Are, Alan Watts,1989)
“This very large thing (the net) provides a new way of thinking (perfect search, total recall, planetary scope) and a new mind for an old species. It is the Beginning. […] At its core 7 billion humans, soon to be 9 billion, are quickly cloaking themselves with an always-on layer of connectivity that comes close to directly linking their brains to each other. […] By the year 2025 every person alive — that is, 100 percent of the planet’s inhabitants — will have access to this platform via some almost-free device. Everyone will be on it. Or in it. Or, simply, everyone will be it.” (The Inevitable, Kevin Kelly)
When the interface becomes invisible
There’s been a lot of wailing and gnashing of teeth over Apple’s announcement there won’t be a headphone jack in the new iPhone. Eliminating the jack leaves more room inside the device and makes it more water resistant, which makes sense but Frank Swain (New Scientist) thinks there’s more going on here.
“Unlike visual interfaces, which demand your attention, audio provides an ideal interface for pervasive, background connectivity. The end goal is a more immersive type of computing, where the interface itself becomes invisible.”
I talk to my iPhone more and more. Google Now, Siri, text-to-speech. And my device (I just don’t think of it as a ‘phone’ these days) is getting better at “understanding” me and giving me the information I ask for.
But if Apple’s new bluetooth Air Pods work as Mr. Swain thinks they will, they might take us much closer to “a more immersive type of computing, where the interface itself becomes invisible.” Suspend your disbelief for a minute or two and imagine me sitting in my local coffee shop with my Air Pods in my ever-larger ears. I’m listening to Bob Dylan.
Siri: Excuse me, Steve, but you have a message from George Kopp. Would you like for me to read it to you? [George is on a VIP list of people I’ve told Siri I’d like to hear from when I’m doing other stuff]
Me: Yes, please.
Siri: George wants to know if you you’d like to have lunch at the fish place?
Me: Tell him I’d love to. What time?
Siri: I’ll check… George asks if noon is good for you?
Me: Tell him it’s a date.
[Later that morning]
Siri: The new John Sanford novel you pre-ordered on Amazon has shipped. Should arrive this Friday.
Me: Thanks, Siri. Put a link on my calendar to the description of the novel. I can’t recall what this one is about.
Siri: I’ve added a link. If you’d like, I can read you the description now…
Me: Okay. Please do [Siri starts to read the description, I remember, and tell her she can stop]
Siri has a standing order not to contact me between 10 p.m. and 7 a.m., unless I get a call from someone on my VIP list. Next morning I pop in one of the AirPods…
Me: Good morning, Siri. What do I have on the calendar for today?
Siri: You’re joking, right? [I’ve programmed Siri to have a sense of humor where she thinks appropriate] Actually, you do have one item. Hattie has an appointment at the vet for her annual shots. 4 p.m.
Me: When was she last at the vet? [Siri has access to my calendar, of course)
Siri: Looks like March 8th of this year. There’s a PDF of the vet’s notes from that visit attached to the appointment on your calendar. Would you like for me to email that to you?
Me: No thanks, I remember now. What’s the big news this morning? [I’ve given Siri a list of topics I’m interested in and she augments that with what I’ve been reading and searching. She reads headlines]
Me: Wow. Can you play the audio (from YouTube clip) of Trump saying he thinks Putin is a great leader?
Siri: Of course. The clip runs 45 seconds.
I could go on (and on) but you get the idea. Before anyone freaks out about Siri… this could Google Now or Amazon Alexa or (fill in the blank). And I’ve given my digital assistant access to all or most of my accounts. (Hey, Siri… when is my VISA bill due?)
Not keen on having a robotic voice buzzing in your ear all day? Chill. It will be as natural and pleasant as any human voice you hear. Even better. [More examples]
Will it seem strange to hear and see people talking quietly to these digital assistants? At first. But it’s pretty common to see people talking via bluetooth devices now. When everyone has and uses this kind of tool, it won’t seem that odd. Remember it would have once seemed strange to see people walking down the street talking on a phone.
No, I don’t think Apple is simply trying to get rid of the little white wire hanging from our ears. This is about a new way of accessing and interacting with all of the information in the world.
Dark Matter
In this novel the multiverse is real (are real?) and the protagonist (and others) can visit these other realities which include other versions of himself. One would expect a novel based on quantum entanglement to get confusing and this one did. (There were moments in the story that reminded me of Philip Jose Farmer’s Riverworld series.) If you’ve ever pondered what you life would have been like if you had taken that other fork in the road, you might enjoy this novel. I found it well written but disturbing. I was eager to get to the end. (Amazon)
The virtual reality of a good novel
VR gear keeps getting better and cheaper and — eventually — I’m sure I’ll give it a try. I have some concern that I might like this technology too much. Don’t think I’ll ever become addicted to VR games because, well, I’m just not a gamer. But I could see myself strolling the virtual back-streets of some foreign city for hours at a time. That somehow feels like a bad thing. But…
I can spend three or four hours at a whack lost in the pages of a novel, oblivious to the ‘real’ world around me. Is there a difference between these two experiences?
