> Options have been this way since the 80s. What's changed? Nobody is examining that as closely as they should. ... we should all possess a certain conservatism, a healthy skepticism to changing systems that have been stable for a long time.

The same argument could be applied to the way VCs used to do business with founders (with respect to tactics, terms sheets, etc). Arguably, that was stable for a long time too (but seems to have changed in recent years). It's just a reformulation of "We've always done it this way".
