I think there’s a lot of truth in Paul Graham’s words. Beware of tunnel vision: if your product is a cloud based solution you may be right, but in many other markets you really need more than one brain and one persons skill set to be successful. My own startup is targeting the manufacturing industry – that’s not a market where putting out a web site on AWS will get you anywhere.

For your case, building alone might be good, for me — for us, it isn’t.
