Other big problem is that today's computers have a lot of memory, it can look contradictory, you need more memory, the computer has more memory and this is bad. Why?
In old Win 3.1 days when you had only 4M memory and 50M hard-disk you were playing some card game and suddenly your screen became corrupted and the computer crashed.
The computer worked normaly, but every time playing this same game the same story happened, so the conclusion was obvious, this game has some bug.
If you investigated a little with some tools you have discovered that the game was using Windows resources and not freeing them, so after some time of playing Windows runout of resources and crashed.
Now you have upgraded your computer and you have 16M RAM and a disk of 512M and you play again the same buggy game. Surprise you discover that nothing happens and you reach wrongly the conclussion that the game is OK and the problem was in your previous computer.
What happened?, the game is still buggy, it uses resources without freeing, but as you have more memory available you will need more time of playing for the computer runout of memory and you only play half an hour, not time enough.
You live happy with your new computer, you can play the game without crashing, but what you don't know is when you exit the game your computer has only 4M instead of 16M that makes other applications to run more slowly, or even crash the computer. Then you blame this other application until you upgrade your computer again and all works normaly.
With a modern computer with 2G RAM, this game never will crash the computer, you will need to be playing for monthes until it crash, the program is buggy but there's no way to realise that this software is wrong.
Having a huge amount of resources makes all the bugs become hidden, specialy the tiny bugs.
But the bugs continue to exist and continue degrading the performance of your computer.
Something that was very visible with little resources becomes invisible.....
With today's computers the number of buggy programs is very much bigger and the program are more baddly done. If you make a software is easy to discover a bug if your computer has only 32M, but if your computer has 2G you never discover the bug and what is worst, people that make a software and discover that it crash with 32M and run OK with 512M,  don't do nothing and put in the system requirements for the software "minimal memory 512M"
Result, minimal requirements : "CTL-ALT-DEL keys and Power Switch".........

Stupidity also evolves!
