what i was saying wasn't either of those, but it's closer to the former: some technical people have a proper superset of the skills of some nontechnical people, because that's kind of the definition of “technical people”

while it is true that nobody is both as good at soccer as lionel messi and as good at programming as jeff dean, you can definitely be good enough at everything to start a company. and lots of people are bad at everything. everyone starts out bad at everything

being bad at programming or biology or whatever the relevant technical field is doesn't make someone good at management or bizdev

so don't look for nontechnical cofounders

just look for cofounders who don't have to be technical
