Ivan Sutherland on the next revolution (and it isn't quantum computing). Note, the Q&A session following the presentation elaborates on these ideas.

I think it would have helped if you linked to the timestamp[1] where he started talking to encourage discussion, 5h47m in for anyone wanting to watch it. I recommend at 2x. It's a very interesting presentation, from the history to the mechanics of how it works, to the possibilities.

It's interesting to hear about how it originated in a research group in Russia led by KK Likharev, and how the students were poached to the USA and are now at retirement age there. That it was funded by the USSR to out compete IBM superconducting and Sutherland thinks[2] his group did with SFQ .

Sutherland was interested in wafer probers for the purpose of SFQ research that work at superconducting temperatures, he asked where he could get one and was told four were shipped to China[3]. Relevant relating to how USA is falling behind possibly, and there are sanctions on nVidia sending the latest in GPU/compute to China, but this happened.

One of the most interesting topics I have been introduced to and a great presentation and Q&A (watched at 2x speed of course) on it.

I'm sorry I thought I did, but maybe I lost it. I'll see if I can fix it.

There's a separate video with just this.
