I think it's mainly anti-AI sentiment in general.
Even myself, while I am currently extremely empowered by these tools... I could see my role (Founder/PM/builder) disappearing in the next couple years.
I respect you a lot, so if you have a moment, I would really like to get talked down from my take.
I still had b2b product ideas, but was never able to raise funding. I built an MVP in 2 weeks, got a co-founder to pay for my beans and rice for the year spent building, getting feedback, and refining. We now have paying users.
