Yes you should investigate other options outside of Python, on a regular basis I keep up to date on other frameworks/languages and on a regular basis I decide that Python is still the right choice for me. If you aren't doing this on a regular basis (at least once a year seriously considering where your framework/language of choice is on the market) then I think there is a serious problem. The CS world changes so fast that you always need to consider if what you are doing is simply outdated and you should pay the cost to stay current. However if that cost still isn't worth it and everything is working on your outdated, legacy hardware and software and you can still keep up with the market than you're good. I simply like to keep myself up with the market/community, when I release new software I try and make sure I'm not releasing something on a platform that will be dead in a month.
