Why the hell stay in in academia? This is clearly the next technological wave, and you shouldn't sleep on it. Especially when you're so well positioned to take advantage of your experience. You can make $500,000/yr (maybe more with all the new startups and options) and be on the bleeding edge.
If you want to go back to academia later, you can comfortably do so. Most don't, but that doesn't mean it isn't an option.
ETA: And though it may take longer, people who understand these models will eventually be in possession of the most valuable skill there is. Perhaps one of the last valuable human skills, if things go a certain direction.
Getting your hands dirty is the best way to understand how something works. Think about all the useless SE and PL work that gets done by folks who never programmed for a living, and how often faculty members in those fields with 10 yoe in industry spend their first few years back in academia just slamming ball after ball way out of the park.
More importantly, $500K gross is $300K net. Times 5 is $1.5, or time 10 is $3M. That's pretty good "fuck you" money. On top which some industry street cred allows new faculty to opt out of a lot of the ridiculous BS that happens in academia. Seen this time and again.
I think the easiest and best path for a fresh NLP phd grad can do right now is find the highest paying industry position, stick it out 5-10 years, then return as a profess of practice and tear it up pre-tenure (or just say f u to the tenure track because who needs tenure when you've got a flush brokerage account?)
$100,000 in 1970 is worth almost $800,000 today.
Yes, downvote me all you want. But if you're an NLP expert thinking of working for a company that will make billions off your work, you can and should demand millions at least.
