I actually do, I completely and elegantly solved a core problem of my niche industry that had been plaguing it for over 40 years. I was already planning on doing it and had put aside 4-6 months to do it. I did it with the help of AI in 3 days. The AI couldn't do it on it's own I had to walk it through the process piece by piece, and it kept trying to avoid doing as I asked by lying to me, so I kept chastising it. It eventually relented and it worked. There was a deep theoretical underpinning which I believe was beyond AIs ability to originate but once it understood what I was doing it was great at the mechanics of it. I've tried to explain similar ideas to humans with much less success.

Now I've massively expanded my scope and I'm still worried I'll run out of work by the end of the year. It's so much fun. Previously I would have to try to convince people with money to fund such applied research and often the strings they'd attach would doom it to failure. I was worried I would never have the resources to test out my ideas in my lifetime and I would die not knowing if they were any good, and since one of the big ones has already worked I'm pretty stoked.
