Really? Even with this very generous 30 year gap ... you think you can run non-toy climate models on a $100 phone? Correlated quantum chemistry for a polyatomic system? Even just fully ray-traced rendering?

And if this was the fastest, the average ones were significantly smaller.
What you're missing is that the things you mentioned sometimes took months to run in the fastest computers thirty years ago, but you are mentally expecting them to work quicker now.
Anyway, interesting talk, thanks. Have a good one.
