I am technical entrepreneur (was a founder and an early employee in several successful and several failed startups)
My main focus over the years were mobility, security and low level development.
However I am strong believer that platforms, languages, frameworks are just tools and it doesn't make sense to put too much emphasis on length of tools usage.
