No, I won't be your technical co-founder
Here's the problem with silicon valley:Engineers think they rule the world.  But in reality, product people rule the world.It doesn't matter if your other "non-technical" co-founder sits on his ass all day and you work your ass off...because you have to understand that one angle of perception--one simple spark of an idea--can create just as much value as your sweat work."Point of View is worth 80 IQ points"When you wrote "Your are easily replaceable"...you are 100% wrong.YOU are easily replaceable.  You're just the coder who builds the thing.  Once MVP is launched and the company raises funding, you could easily be replaced because I guarantee you there are thousands of engineers just as good as you.The product guy, on the other hand, is the DNA of the company.  He forms the vision, culture, management.  You can't replace that.
