New breakthroughs in general - can't rely on them in the same Moores law sense, but they still happen

I'd also argue I don't know that scientific progress has slowed per se, more we've sort of finished our backlog of stuff and it's just the newer stuff that's less easy to come by.

There's also the idea of, everything in retrospect seems faster - get a good list of the year to year big stuff, it might not be that different, but if like 6 big things happened in 2011 or whatever and you're like "eh nothing big has happened in like 2 months", those two months feel a lot closer, pressing, than the 2011 two months per event on average
