That was very unconvincing.

Like if you want to go from history - yes the make a giant artillery piece thing didn't work.

You know what did work? A surprising application of quantum physics known as nuclear bombs.

I'm not neccesarily saying quantum computers will work out the same way, but if you follow the logic of the presentation, nuclear bombs fit it so much better than the example they use. It was a step-change. People went from saying it was theoretically interesting without practical application to actually having a bomb very quickly. Basically replace everything in that presentation using nukes as the running example and suddenly the argument sounds really stupid.
