Yes libraries and infrastructure do not give you insight like a co-founder, but a large part of an engineering co-founder in a heavy engineering startup is perhaps %80 - %90 showing the strength and attention to getting the development right. For example managing an engineering team, showing attention to detail, making sure the design is exceptionally good etc. He has these two crucial pieces of technology at hand which would otherwise be developed by using most of the energy of a tech cofounder. So in that respect I agree with the point. In summary, there are now tools to make it so much easier for startups that sometimes they can even do almost as much as a technical co-founder.
