As far as 'meek guys' turning to jerks with a taste of power - it's very common for all types.
Without going into my background I had a chance to witness 100's of young people come into, and go out of power. Almost everyone 'over identifies' with their power when they first get it. It takes 'coming out of power' to have self reflection and awareness about it.
Tragically - so many people in their careers just go 'up' the power ladder and never develop any awareness. It takes going 'down' or 'laterally' a few notches to really internalize the lessons.
The situation I was in, I witnessed a lot of 'power rotation' i.e. people taking turns being lead/manager. It was a really, really powerful thing. Though this was not in high tech and a completely different field, not sure it would work in tech.
