There's a difference between talks for invenstors/entrepreneurs, and talks about fixing a massive clusterfuck of government spending.

Especially when the narrative people want to spin is "Gee golly whiz look at those Silicon Valley folks saving the day!".

Anything else is CYOA, and it'd be nice if people could actually rise to the occasion and be honest and precise.

(Besides, if you are honest on everything, and somebody just hits you out of context, you can defend yourself by providing additional context. None of this is going to matter in 5 years anyways, so might as well set a good example.)
