I'm not saying the regulatory environment is wrong. I'm saying the market it creates (aside from avionics) is not a good fit for innovation stemming from venture capital due to venture capital's expected return magnitudes and timelines.

I cited three technologies (ICE engine redesign, low-lead gasoline, and lithium batteries) where those timelines for market adoption (outside of GA) were orders of magnitude (decades) shorter.

My comments were solely targeted at GA. Commercial aviation is an entirely different ball game.
