Those that are comfortable taking this risk can simply issue a LIMIT order instead of a MARKET order.
You thought wrong. While there are a variety of things that HFT firms do, most of it is market making.
An analogy might be something like Uber and Lyft competing with each other for clients and drivers. From the perspective of everyone else, it doesn't matter much if they ride Uber or they ride Lyft. But the adversarial games that they play against each other [Uber and Lyft] are beneficial to both riders and drivers. Perhaps a duopoly isn't the best example, so you may extrapolate this to any industry where there's a sufficient amount of participants to keep things competitive.
Moreover at this point speed is a commodity, if you're willing to shell out cash, you can get access to top tier infra right out of the gate. The real game is not how fast you are (though obviously that's important too), but how smart you can be while maintaining good tick-to-trade latency.
Trading has never been a vanilla/boring business and it likely never will be either.
True but not something that I find compelling. If you can only compete on price in penny increments, then you'd have to be hugely more confident to undercut a 1c spread with a 2c spread; if you could offer a 1.8c spread by taking a little more time over your calculations, that would change things.

I mean yes, to the extent that there's profit in it at all. But the profits have already been shrinking year-on-year. Plenty of mature industries like supermarkets are utterly cut-throat, but don't bother regular people.

Well, it's the same thing, like the project management triangle - you can always trade quality for speed and vice versa, the hard part is when you want to improve both. But I do agree that at this point a lot more of it is known quantities and techniques.

My sense is that it's no longer where the best and the brightest go (and as I said before, profits are shrinking a lot). More and more of it is commodified. Which is what we should expect from any industry, honestly - at some point things are new and exciting and profitable, then they become mature and less so.
