Who wouldn't ;-) Thanks to the transition to asynchronous message based communication I can have more and more meaningful communication with a larger part of my family than I would if I had to FaceTime or call them.

Here’s something else that they didn’t predict: that sales of books printed on paper are at their all-time highest now.

Think of data centers as huge mainframes and we will soon come close.

> Think of data centers as huge mainframes and we will soon come close. I... kinda doubt it. All of the really big players have access to markets that are willing to pay huge margins. there are a lot of smaller players that would be happy to sell you compute at 75% the price of amazon, and bandwidth at 1/10th the price of amazon. Yeah, the big customers are happy paying the premium, but there are plenty of small cust…

It's going to be increasingly difficult to compete with the big players' economies of scale though. There's a reason we don't buy cars from the neighbor's factory or generate our own electricity these days.

I must mention my favourite sci-fi short story, "The Machine Stops" by E.M. Forster[0]. It is from 1909 and is chillingly prescient.

Essentially, a machine provides all necessities of life in a persons' pod, so they need never leave. People spend their time making essentially YouTube videos about their opinions. Nobody cares about facts or knowledge anymore. Spoiler, it doesn't end well for them.

I have always thought science is inspired by fiction. Cellphones are nothing less than a better communicator, Bluetooth badges are even available on thinkgeek!

A large portion of tech is conceivable way before it is possible. E.g. self-driving cars and sentient AI robots have been written about for a century already. Doesn't really mean research into those is inspired by the stories.

For something that was conceived in a very public way (e.g. a popular work of literature), I find it hard to believe that research wasn't inspired by the stories at least in part. Not the fundamental research in other fields that made it possible in the first place, perhaps, but the final engineering work.

At my university there are several ironic and funny posters with quotes about mispredictions on display at the walls of the big lecture hall of the mechanical engineering building. My favorite one is from Gottlieb Daimler 1901: "The global demand for automobiles will not exceed one million - at least because of a lack of available chauffeurs." [1] He is the founder of the predecessor of todays Daimler AG, which owns…

Maybe he was just trying to misdirect the competitors, while himself building up capacity to sell a lot more cars.

It is, but rather difficult and expensive for short to medium distances. Submarine power cables are often HVDC. https://en.wikipedia.org/wiki/Pacific_DC_Intertie

Great article. The thing's grounding system is lustworthy: The Sylmar grounding system is a line of 24 silicon-iron alloy electrodes submerged in the Pacific Ocean at Will Rogers State Beach[4] suspended in concrete enclosures about one meter above the ocean floor. The grounding system at Celilo consists of 1,067 cast iron anodes buried in a two-foot trench of petroleum coke, which behaves as an electrode, arranged i…

Incredible! I've always been fascinated when driving by the Sylmar station (many times in my life) and never knew that I was driving by connecting infrastructure when on PCH in that area.

And even more interesting is they are replacing/replaced it! https://www.circlingthenews.com/terminus-of-sylmar-ground-re...

He perhaps had read the novelization of 2001, published a year earlier:

--begin quote--

There was plenty to occupy his time, even if he did nothing but sit and read. When he tired of official reports and memoranda and minutes, he would plug his foolscap-sized Newspad into the ship's information circuit and scan the latest reports from Earth. One by one he would conjure up the world's major electronic papers; he knew the codes of the more important ones by heart, and had no need to consult the list on the back of his pad. Switching to the display unit's short-term memory, he would hold the front page while he quickly searched the headlines and noted the items that interested him.

Each had its own two-digit reference; when he punched that, the postage-stamp-sized rectangle would expand until it neatly filled the screen and he could read it with comfort. When he had finished, he would flash back to the complete page and select a new subject for detailed examination.

Floyd sometimes wondered if the Newspad, and the fantastic technology behind it, was the last word in man's quest for perfect communications. Here he was, far out in space, speeding away from Earth at thousands of miles an hour, yet in a few milliseconds he could see the headlines of any newspaper he pleased. (That very word "newspaper," of course, was an anachronistic hangover into the age of electronics.) The text was updated automatically on every hour; even if one read only the English versions, one could spend an entire lifetime doing nothing but absorbing the everchanging flow of information from the news satellites.

It was hard to imagine how the system could be improved or made more convenient. But sooner or later, Floyd guessed, it would pass away, to be replaced by something as unimaginable as the Newspad itself would have been to Caxton or Gutenberg.

There was another thought which a scanning of those tiny electronic headlines often invoked. The more wonderful the means of communication, the more trivial, tawdry, or depressing its contents seemed to be. Accidents, crimes, natural and man-made disasters, threats of conflict, gloomy editorials - these still seemed to be the main concern of the millions of words being sprayed into the ether. Yet Floyd also wondered if this was altogether a bad thing; the newspapers of Utopia, he had long ago decided, would be terribly dull.

That depends entirely on the voltage. AC won because transformers are relatively simple and can change AC voltage, but we can now build stuff to change AC voltage too.

Arguably, it's now cheaper in raw material terms to up-step and down step DC with high frequency transformers and buck-boost. The problems are lower efficiency than a modern, high efficiency transformer, which leads to increased dissipation and lower life of the complex electronics involved, requiring active cooling. An AC transformer is a well understood technology that can operate for decades without any maintenanc…

People are already building 802.3af and 802.3ad based office LED lighting systems at 48VDC, since it's much cheaper to run cat5e around a big building.
