I remember in 2013 I spent $3000 on the latest everything and built myself a new PC. My wife walked in just after I got it running and looked at me; I had graphs and spreadsheets all over the screen. "I can tell you're not working. What on earth are you doing?" "Calculating how far back in time I would have to go until my PC was the fastest computer on Earth. 1992 is the answer. It would be faster than DARPA's $90m supercomputer that filled a warehouse. If I go back to 1984 my PC is actually faster than every computing device on Earth, combined." "I'm sorry I asked."
