I would like to devolve to being the AI engineer in an engineering team that I (initially) build around me. Eventually someone else - a CTO - would build it up further. Thus the PM, who is supposed to be working with the engineering team (at the moment just a MERN engineer and me) and first users to turn my (fully working, but ugly) prototype into a scalable, usable product.
