php vs other modern language

Unwillingness? Rocs, you make me laugh. Since the end of my C programming career in 2003, I went back to get an MBA in Accounting. Why? I got sick of the ever changing language learning requirements of the "developer life". (Beer, I'd love to hear your opinion of that decision since you clearly took the other road, message me).  I ended up getting a job for the IRS where, to this day, I still audit software tax credits of some very, very large software companies around the US. I also have done some work on tax regs affecting software. So Rocs, I don't think "unwillingness to learn more about PHP" is a fair measure of "laziness". Have my development skills degraded since I was a pro developer?

Surely. But i can pretty much guarantee that I know more about the taxation of software development projects than your "average bear".  Does that make me unwilling to learn more? I don't think so. I just am concentrating on different "technical issues". Between my engineering education, my Accounting Education, and my 16 years of knowledge of the US tax code, my brain is fairly tightly packed. At this point I need to be careful to only add new info that is important in the short term.  At 63 is there a "long term" ? 

I am a life long learner and that is why I couldn't imagine that modularity was not being addressed in PHP. So thanks for that information. Being one of the few software taxation auditors at Treasury, I don't really have other engineers to talk to about modern programming paradigms. I do attend AWS free trainings as much as possible, but I need much more. 

Again, thanks all for the valuable answers. You guys are kind to share your insights.
