The EE/IC Design part of me loves this for trying to build a community around what is typically a very opaque and secretive industry. The social justice / millenial part of me hates this for being funded by high frequency trading, of all things. What a colossal waste of resources.
I don’t think Jane Street does high frequency trading. I think you might be thinking of Citadel or HRT. Jane Street is more of an old-school quant hedge fund, no?
Their bread and butter was, and as far as I know still is, trading in ETFs and ADRs. These things have a mechanism to create and redeem in exchange with underlying securities. This means one can make some money arbitraging differences between the bundle and components.
As this game got more competitive they seem to have branched out into other kinds of business including HFT.
