Memory protection forces programs to be clean and properly use proper APIs rather than pilfer around public OS structures and fuck things up for every other well behaved tasks.
But the problem is that sometimes accessing public structures is a necessity for the job we're going to do. Think about monitoring software or OS patches.

A new OS could give extra privileges to trusted software to overcome this, though.

A program that crashes will crash, memory protection doesn't change this.
So you have to filter out bad software anyway.

Think twice. Intuition.library constantly sends messages to apps.

I second that. Being tolerant to errors indirectly raises the number of said errors.

This gets us back to the chicken and the egg problem.
Even the best compiler in the world won't turn a messy program into a good one. And most of the software we don't have (good browser for example) are nothing but gruesome bloatwares.

While asm can do wonders, in some cases the task is simply impossible.
So even though i would love writing an AAC decoder that does real time on 030, i know it won't happen. And i'm not talking about watching youtube videos.
