> And what the past sees as hard often becomes less hard (I'm not going to say easy, because technology is never easy) in the future thanks to the accumulation of knowledge and increased speed of processing data.

It doesn't matter how fast you process data if you can't physically alter the scenario. No amount of data can make the carnot cycle more efficient or reduce entropy.

I'm sure the Romans thought Europe would never enter the dark ages too.

Particle physics has been at a standstill for decades. Fusion power is still a pipe dream. Global warming continues to go on without a technological answer in sight.

False AI promises are not evidence of anything. Nothing AI is doing now is genuinely artificial intelligence. Biotech? We still can't cure cancer.

We are getting more and more evolutions and less and less breakthroughs. That, to me, is slowing down. That doesn't mean things won't get better - just not as quickly, or as thoroughly.
