Earlier quoted context omitted.

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.

Don't forget that three phase allows for three conductors to carry the power of three pairs of single phase conductors.

Alternatively, skin effect limits the amount of AC current you can throw over a single conductor. With DC, you can make your conductors arbitrarily thick and you'll use the whole thing.

If this quote is from September 1969... The movie 2001 was released in late spring 1968. In it the astronauts are using a color tablet computer laying on a table, no thicker than a modern iPad, to watch video. https://www.bfi.org.uk/news-opinion/news-bfi/features/did-st...

That movie is very special. A lot of it’s predictions like flat LCD screens, personal IFE on airplanes, iPads, and kids messing around on FaceTime are so mundane now it’s easy to overlook them when watching the film with a 21st century set of eyes

Yet its central “prediction”: that human travel into space would progress forward at a comparable rate to what was accomplished in the early 60s, was wildly off.

Earlier quoted context omitted.

"I think there is a world market for maybe five computers." Thomas Watson, president of IBM, 1943

1889: “Fooling around with alternating current (AC) is just a waste of time. Nobody will use it, ever.” — Thomas Edison.

Edison made money off of selling DC infrastructure though.

Three-phase AC also allows for very electromechanically simple generators and motors. Industrial electrical loads have traditionally been (and often still are) rotating machinery, putting three-phase at an advantage.

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…

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

Those working in the industry often know what's coming. What they often get wrong is how it's economically deployed, when it arrives, or what effects it will have.

E.g. the first articles on capacitive touch screens dates to the 50's, and the "flat-panel" Aiken tube display dates to the early 50's as well:

Article on the Aiken tube from 1958 with pictures that predicts future models may be flat enough to "hang like picture frames":

Seing the potential of going from normal TVs to that, it's certainly not a big leap to assume they'll get even thinner and smaller.

Bell had a video telephone demo at the 1964 Worlds Fair in NY[0] some five years prior to this NYTimes story

I think a lot of public ideas of the future sprung out from that

I don't think the quote refers to a portable telephone but rather of the style that was demonstrated at the World Fair
