I'll add a comment that hopefully won't get buried. The hard problem that Rovelli is talking was, I think, the first time someone said something in the field of consciousness that people could (at the time) agree on. Not many people were openly discussing in the 90's in academic settings.

It was proposed by Chalmers as a young undergrad at the Science of Consciousness conference. I have been attending for awhile and really enjoy it. There are so many opinions and thoughts on this post, if you are really into thinking about consciousness, this year the conference will be in San Diego. It's a long day of lectures, followed by evenings of great conversations. https://cs2026.org/
