Depends on what you are doing. Betting on C++ was a good idea for me 20 years ago - but I work in embedded systems where Java wouldn't work because I sometimes need to access hardware. Embedded also means I don't even have a web server, so I have no need for a web framework which the person you replied to seems to find important. I don't know their situation, but there is a large need for people to write web code and so for many people betting on a web framework is a good idea.

I have done enough web to know I'd bet on python over PHP, but only because I know there are several popular web frameworks in python to chose from.
