The amount of money spent on software development was a lot smaller and there were far fewer programmers. And they were creating a lot of bloated nonsense that you could install on your 8086, commodore 64, or whatever. Windows 1.0 is a good example. That was released nearly 35 years ago.
These days the one thing that's different is that hardware ages a lot slower. I've been on several laptops with 16GB since 2012. Back in 2012 that was a lot. Now Apple seems to still find 8GB more than enough for anyone (Bill Gates pun intended). Things are moving much slower with hardware.
