More than ever before, finance is a quantified world. Nearly all stock trading is now done by quantitative traders, or by the computer algorithms they’ve developed. On the buy-side, the world's largest hedge funds trade using systematic models, whilst the rise of passive indexing means that fewer investors are pinning their hopes on traditional stock pickers.
These trends are making some people very wealthy. At the top of the tree owner managers of large quantitative hedge funds like James Simons (Renaissance Technologies), Ray Dalio (Bridgewater), and the UK’s own David Harding (Winton) regularly hundreds of millions or even billions.
Sadly the same cannot be said for most quants, who have to toil in the trenches for relatively small pickings. Almost none will ever earn the seven or eight figure pay packets that senior traders and portfolio managers view as a just reward.

I am currently working on my own commercial tech. Good news...if it is profitable just me and whoever else may join the venture gets all of the profits. Bad news...I am currently bleeding money each month. That is the trade off and I am happy with it. Also, I have never seen a group of average devs create above average results. What usually happens in practice is you one or a couple of strong devs (maybe rock stars) and they spend part of their time coaching the other team members.
