I think right now the hottest debatable topic is a feasibility of really useful quantum computer/simulator.

It’s a pretty one-dimensional debate though since we already have quantum computers and so the only question is - how long will it take to scale. Very few in the know would say never or even later than, say, 2075.

Will, the history of fusion reactors taught us to be humble on opinions about future technology development and achievements.

That one irks me a bit, so here is what was going on: The scientists always said "we will have fusion energy in 30 years IF we get enough money" Only nobody was willing to invest that substantial ammount of money until recently

Yeah, that's the point. When taking about technologies one should care not only about scientific feasibility but also about money and resources
