> Computers were slow in the 80s/90s, so if you wanted your program to run fast, you had to know how cache and RAM worked, and utilise what little power was there to the max. As computers have gotten faster, that knowledge has gotten less relevant to the average developer.

Yes and no here.

I fully remember the same thing happening slower computers back in the day. My Amiga 500 was this way as I recall. That was a computer released in 1987, until I finally upgraded to a PC circa 1996/7 ish.

There was a point where MS was releasing slow software on purpose with the idea that the processors (which were still following Moore's law) would catch up and make it fast. Though one has to wonder if it was secretly Microsoft's inability to write good software that drove Moore's law.
