What about the people who should have been rejected? Surely, with so many companies there are companies where rejecting them was a service. Now they are instead getting that validation which might make them go on working on something obviously fruitless. It might not even be their own fault, it might just be that no one in YC is really excited about working with them and you can't offer much else which you should be up front about. It is of course admirable that you want to make things work, but I definitely wouldn't underestimate the challenge of transforming your whole process retroactively.

I don't know. The fair way to handles this would have been to first honour the original deal. They have already put people through the application process and the were going to reject them if this hadn't happened. Instead of "accepting everyone" they should have rejected the ones original being rejected and then asked them forgiveness and confidence in this additional track. Now they have left a lot of people in the awkward position of doubt if they want to do it but without an easy way to say no.

Per game. Still it is a weird design choice for something where you need a lot of people to move at the same time. They need to decrease the distance of the skates, chain them together or get bigger ones. Automatic people movers are nothing new, but if this is what it takes for the US to be excited about infrastructure then I am all for it. Half of the utility if these types of systems tends to be in the overall design though. The interior of the vehicles, the location and design of the terminus, how long you have to wait etc.
