YC should back duplicate startups because each startup's chance of success is low. If it makes sense to back a startup with a 10% chance of being a big company later, then a second such startup also makes sense, even if there is a 1% chance that they both make it and one of them is not needed. The problem is when someone says the quiet part out loud, and the duplicate startups start talking to each other. The people at one startup refuse to do useful work because they incorrectly believe the other startup have a better idea. You want to leave those decisions to senior management, who can move technologies to make one company successful. Have you ever suddenly received an influx of employees because someone jast realized that there was a duplicate company doing the same thing (fake gasp) and that it was time to combine the best parts of both the get a product? Somehow, despite nobody knowing there were duplicate startups, a proof of concepts has been working for a few months combining the best bits from each of 3 (fake gasp) startups, and the third one had very little to contribute so you will not see their people around. I'm sorry if my post hurts anyone's plans. Fell free to delete it.
