Mute said:Assuming that all physicists are going into finance to cash out and are going to screw everything up is silly
And even having physicists cash out is not necessarily a bad thing. I'm hoping that a decade from now I'll have a fat bank account, and be using it to fund my own research in supernova and high performance computing. I'll also have a ton of experience in things like management, finance, and politics which I'll be able to use to do astrophysical things. Right now, "I want a moon base" is idle talk. When I have money and political connections, then I can effectively lobby for moon bases.
Ultimately, the reason I went into finance was that I want to study astrophysics. If someone has a better plan than make a ton of money from Wall Street and then cash out, I'm open to alternatives...
Now a critical part of this strategy involves not blowing up the world...
I can hope for stuff. I can pray for winning the lottery, or I can actually do something that gets me what and where I want.
Because he's talking about what "quant types" are doing now, as opposed to back in 2005:
Which is pretty relevant for someone looking to get into the business now. Now what the world looks like in 2017, I really don't know. I subscribe to the "pinball model" of history and finance. If you want to know what the world looks like tomorrow, then it's going to look a lot like what it looks like today. If you are trying to model the motion of a pinball, you can use the same principle until it hits a bumper at which point it's going to fly off in some random direction. (I did some work in chaotic billard systems.)
As time passes the odds of something happening that causes the "straight-line" approximation to fail increases until it hits one. You can deal with this sort of system using Lypanov exponents and timescales, so the time scale for "history hitting a bumper" is roughly two to three years.
Also it matters when you hit the bumper. For example, right now there really isn't that much point in talking about financial regulation, because all of the big decisions were made two years ago, and no one wants to revisit them and undo the deals that were being made.
