That does seem like a much more effective plan than my "fuck around in the 90s" scheme, yes. (Though I was assuming a somewhat pre-stockmarket approach re: google funds; my money is so much more useful if I can use it as part of the angel investment and such; this does mean that you're in the eye of history a lot more though, but such is the price of trying to obtain personal power through "right place, right time"; actually now that I think of it, it'd be kinda fun to iterate on that - do the same thing four or five times, just compounding resources; it's unrealistic, you'd muck with the timeline too much but wow would it be funny to be known in secret circles as "That one immortal guy who comes out of the woodwork to make The Perfect Investment" like a capitalist doctor who)

(These answers are all assuming that changing the world is off the table; do you think there are any tipping points you could constructively/interestingly put a hand on if you actually had a time-machine and were willing to re-write history? That last one seems like it'd be a really big caveat but you're *good* at these plans and I want to here what you have to say. I'm gonna take a stab and guess that smallpox vaccines will be involved?).
