Let's become rich?
You don't need to tell me twice. But without more details, it is difficult to act on this suggestion.
(Most people's baseline is not zero. For example, I already have a job that provides a regular income. So I don't need just any plan, but a plan that I would believe is realistic and likely to make more money.)
Given a finite amount of resources (you may notice you have <=10 fingers and <= 2 eyes and a brain that computes at a finite speed) you cannot compute a better answer than the (information you have, cognitive resources you have to consider those resources, a rational algorithm)
The best opportunity to become rich recently was cryptocurrency. But it's price is completely irrational! There was no way to predict this opportunity was real. Not only is every coin backed by nothing but scarcity, each could potentially be banned by governments, any given crypto may have a latent security flaw that allows it to be robbed, there are thousands of competing crypto and ultimately the winner may be no current coin, and so on.
Any rational analysis (which starts with priors from the last century of financial history!) would have concluded the natural value of crypto is close to zero as it's basically a pyramid scheme.
Apparently that analysis is wrong.
Being rational means you have to accept the fact and update your theory, but it doesn't mean your original guess will be the right one! In fact, as I said, a true rational agent weights in all the data it can, which means it will consider all prior financial history including every previous valueless commodity like tulips, e-gold, shares with Bernie Madoff, and so on, and factor in the fact that they all went ultimately to their true value of zero!
Eliezer Yudkowsky says money is the unit of caring.
I note that money is the unit of being able to buy things.
It therefore behooves me, someone who aspires to be more rational, to become rich. Time is money, money is time, and opportunity and happiness too.
How does money buy happiness? If you aren't living socially saturated with the very best people you would custom select from across the entire world, money would help. If you spend any time whatsoever doing things for money, that time-energy would be entirely freed for meaningful pursuits. I struggle to imagine that LessWrongers would be unable to do vastly better, if given infinite dollars.
And notably, money allows others to be the instrument of our rationality. If we constantly come up with ideas that aren't put into practice, this may be the greatest multiplier of all.
So then, if having large amounts of money is of such colossal worth that it multiplies many facets of our life by massive amounts, each of which compound the others...
