Moving stairs is likely the only thing in the article that has a possibility of happening... NYC politics is broken. Nobody is willing to spend money on important projects, the incentives for politicians simply focus too much on the short term. Changing the geometry of the stations at certain bottleneck points could have a significant effect on delays caused by overcrowding. I've noticed this sort of thing during rush hour, where a train has to sit in a station for an extra few minutes as people push in.
