Probably Bill Gates, for nearly single-handedly making society associate computers and technology with unreliable crap
(and ugly "designs" that show a complete lack of taste).
It should not be "normal" that your computer crashes 10 times a day, that have to constantly deal with viruses, that your computer gets "tired" (slow) after a while and you need to reboot etc.
It's a tragedy that most people think "that's just how computers are".
I've been happily Microsoft-free for years and I'm hoping to keep it that way.
I see, @Tim
and I posted at the same time. Funny, I see you put Microsoft second.
And you are right. I can't stand people who write code (or do anything) like Lerdorf.
I can't imagine being that sloppy, even for in-house tools, let alone with publicly released software...
As the founder of a small startup, sometimes I miss having the paycheck I got at my previous job, but then I realize:
Hey, at least I don't have to work on Windows!
(and, of course, I absolutely love my current projects).
Imagine where human kind would be, if the library of Alexandria was spared!
Imagine where human kind would be, if Windows, with it's horrendous "design" never became the dominant OS!
There is hope though. Thanks to mobile, the market share of Windows has been declining. It went from 94%+ a few years ago, to around 60% today, and dropping at an accelerating rate.
Yes, Dennis Ritchie's passing was a great loss. I use C and UNIX (Linux) many hours a day. All my project are built on his work...
