True, also the industry prefers younger population coz they can burn more hours and are available for a cheaper than the experienced folks.
Also, the industry somehow seems to stereotype a developer as some younger geeks. The stereotype works against experienced folks sometimes (not always).
If we had a sane choice we would still stick to tech - tech is like the first love that is going through a rocky phase!
I believe there is the "collective stupidity" problem in the tech industry where a new framework pops up almost everyday, a new language every now and then and the sheer volume of knowledge to accumulate to stay relevant is abysmally high! With the realities of life taking over, the path is inevitable to most senior people.
