Nice easy shot at Robinhood of course, but they're a very young company. Do the big banks really have a fundamental edge that's not just more invested hours?
- msandford 7y agoI think the idea is that your locks and threads are so close latency wise that you only need a few to get the job done. Versus trying to figure out how to parallelize things, some of which are inherently non-parallelizable. But sometimes you don't know until you try! Ain't life grand?
