I know a company that still has its product in ColdFusion. Just because you are not “hot” anymore means that all your code goes away. The problem that PHP has are not that it is dead or going away (not going to happen). The problem it has is that there is a lot of old code out there. You are probably going to work on something preexisting rather than something new and cool or worse, work on endless customizations to shops, CMSes and so on. Ruby is interesting on the list though. I wonder how much of that is stuff like gitlab, redmine and so on and how much of that is in house software?
