Hardware and Software startups are sufficiently different in their needs and life cycles that it would be specious to use the success of a particular program for the one as indicative of its suitability for the other. Similarly, the sorts of b2c startups that YC typically funds are sufficiently different from b2g startups like Palantir that I don't think you could claim Palantir would have benefitted from YC based solely on the experiences of b2c startups.
That is true. A better way to think of it, might be as an experiment. Do you remember when YC was started funding startups? The tech group-thought at the time: a toy, a joke, nothing serious, never to gain traction.

I don't mean to insult you or criticize your post in any way, partly because I agree with you, but that is a lot of qualifiers for one short sentence. Diplomatic tones require them though, I suppose.
