So there are a few different sources of optionality from a PhD: - Academic credentials - Technical skills - Research skills
Software engineer at a quant firm plausibly builds more general technical skills, but I expect many SWEs there work on infrastructure that has little to do with AI. I also don’t have a good sense for how fast quant firms are switching over to deep learning—I assume they’re on the leading edge, but maybe not all of them, or maybe they value interpretability too much to switch fully.
But I also think PhDs are pretty valuable for learning how to do innovative research at the frontiers of knowledge, and for the credentials. So it seems like one important question is: what’s the optionality for? If it’s for potentially switching to a different academic field, then PhD seems better. If it’s for leading a research organisation, same. Going into policy work, same. If it’s for founding a startup, harder to tell; depends on whether it’s an AI startup I guess.
Whereas I have more trouble picturing how a few years at a quant firm is helpful in switching to a different field, apart from the cash buffer. And I also had the impression that engineers at these places are usually compensated much worse than quants (although your earlier comment implies that this isn’t always the case?).
Actually, one other thing is that I was implicitly thinking about UK PhDs. My concern with US PhDs is that they can be so long. Which makes me more optimistic about getting some external work experience first, to get a better perspective from which to make that commitment (which is what I did).
That makes sense, thanks for the extra colour on PhDs.

I’ve heard variants on this a few times, so you aren’t alone. To give some extra colour on what I think you’re gaining from working at quant firms: Most of these firms still have a very start-up-like culture. That means that you get significant personal responsibility and significant personal choice about what you work on, within a generally supportive culture. In general this is valuable, but it means there isn’t one universal answer to this question. Still, some candidate skills I think you’ll get the opportunity to develop should you so choose.
(This list is illustrative based on my own experience, rather than exhaustive. Some of the above will apply to the PhD as well, it’s not intended as a comparison)
