I agree with most of your statements. But you realize the whole discussion is about Non-Technical Co Founders chasing Technical Co Founders. If people are chasing the Technical Co Founder (at meetups, at industry dinners, at hackathons) why is it on the Technical Co Founder to go thru a full interview first? Shouldn't the person doing the chasing justify their side first?
As a technologist being cornered, am I obligated to do a full interview every time someone has an unsolicited idea and approaches me? Or can I just enjoy hanging out with fellow technologists at Hackathons?
I have literally gotten people pitch me ideas at cafes where I go to relax. Am i obligated to now do an interview on the spot? If random people started demanding unsolicited job interviews I think that would piss off most technologists.
I don’t disagree with the fact there’s tons of non-technical “idea-only” dreamers running around. Definitely more of them than engineers.
But the type of people that OP described are far more rare than software engineers, who are dime-a-dozen by comparison.
Maybe a little humility is in order here?
