Dude, you just got to get the fuck out of Silicon Valley. Tech in general has been raided by finance douches. You need to find a medium sized, profitable company somewhere not in california, new york, or florida, and go work there. You can mentor people and enjoy your life outside work and generally explore tech as you please.

My observation is that many "old-school" tech people weren't replaced by finance people, but became them. Silicon Valley today is Wall Street of the 80s. VC Twitter is a meme. The common folk are waking up to this, thankfully.
