Some things I see, I think: yes, you’re doing that very well. But I understand what you’re doing, and I could, if not do it myself – I could understand how to train to get there. Like running a marathon in not-much-more-than-2-hours. I’m never going to do that, and even if I trained I couldn’t, but I can roughly understand what’s going on. With this, I can’t even imagine my brain and hands working well enough to get anywhere close to this.
After this, it seems to me that the human race has realised its ultimate potential; no further progress is possible. We might as well all go back to bed.
