We are all doomed!
Now, seriously... our IT industry runs on some very wrong assumptions. ("ass" is the word)
We assume that software has to be insecure and prone to bugs and crashes, and that nothing can be done to fix it. We have to thank Microsoft for this. And after them, every software maker has decided that it was OK to sell bug-ridden and insecure software, to maximize profit. And since software crashed a lot, hardware vendors began selling crap hardware, no one will notice anyway, since the computers keep crashing all the time.
And here we are, running crap software on crap hardware. Oh, sure, it costs less than a half (or maybe far less than a half) of good software and good hardware, but would you bet your life on it?
Well, if you use crap software and crap hardware to run critical infrastructure, you are actually betting your life on it.
I mean, come on... windows should only be used to play videogames, and any software that has blatant security issues like a hard-coded root password (which is not a bug, it's by fucking design) should be just laughed at and thrown away.
PS: Please excuse me for my poor english.
