For starters only one line in the system has CBTC, the L train. The 7 line is in the process of being upgraded and they are putting the new trains on the 7 that can run on CBTC. But this process won't be over until 2016. The Queens BLVD line will be the next line to get CBTC. They are currently upgrading the signals and switches and next year will upgrade the rails (replacing wooden ties with concrete ties and continuous weld) to end the rail breaking problem. After this they'll upgrade the other lines.
The older trains (r46s and r68s, and r62 on the 1, 3, and 6 trains, the trains with the bucket seats, and the old r32s on the C train and the few old r42s on the J train) cannot run on automation so these old trains would need to be replaced.
I believe it's due to insurance. Without a human operator, there are more chances that a person can get injured by the closing of the train doors. Subways can get hectic during rush hours. If technology gets better I'm sure they can put out a very safe and fully automated train but at times you do need human involvement in case of crime or accident happens someone has to take control.
It seems like every technological leap that saves labor just means that people lose their jobs and those remaining are given the work that is left over and often overburdened.
I saw promotional materials from the 60's that showed families at leisure in fancy homes as robots brought them drinks and did their work. lol

Do you have any evidence of this? In Paris, they have trains where the door opens when you press a button. The button is disabled when the train is about to move. I imagine most of the problems with closing the doors are due to service delays, which is also caused by the MTA.

The mta is not putting new train cars on the 7 line. The Mta is moving 10 year old modern 6 train cars over to the 7 line and moving the two decade old train cars over to the 6 line. In matter of fact I see more of those older train cars on the 6 than I do with the more modern train cars.
