Before I "upgraded" to Windows 10 (yeah, I seriously regret it ...) my editor of choice was Word Perfect. Version 4.2. For those of you not old enough to understand that, it was written in 1985. I used it for 30 years. It worked just fine.
It was, as far as I know, the last commercial program to be code optimized.
Lest you think this is just another rant from an old IT curmudgeon, it does have a security point. Complexity is the enemy of security. It's not just that now, in order to run these bloated applications, we have to have multi-core CPUs that are subject to race conditions or give away secret information. It's having to have 150 megabyte programs just to draw a keyboard on a screen. (Yes, I know we get autocorrect thrown in. Not everyone considers that a benefit.) When we used to have viruses that clocked in at hundreds of bytes (and, yes, I know even malware has gotten bloated these days) how much damage can you do with that much space to hide in?
