Yes, sorry I replied to a different interpretation of your question I guess.

I was trying to say that YC may be looking past the solution to the real underlying issue.

To me this would make sense. We often start out with a problem that bugs us, and then come up with a half baked solution.

Even if the proposed solution isn't valid the founder may have identified a valid problem. In our crowded marketplace, a unique and unmet need is much harder to find than a technical solution.

Please. That is quite unwarranted.

I happen to agree with the GP sentiment - business is an emotional endeavour, and treating it as such is a good idea.

Often, a cigar is not a cigar.
