From my standpoint as an owner, I've yet to see solid benefits.
Electric equipment are quiet but don't go very far before needing charging. We bought a bunch of greensmowers to assuage the neighbors but switched back fairly quickly. This was 5 years ago, though, so the tech may have improved. Can't speak to hybrid.
Fully automated mowers don't save a whole lot of labor because you need someone to take it from hole to hole and stand around in case it screws up. Yes, they can rake bunkers, but the mowers are slower, so there's some wasted time. The ones I looked at cost 2-3X what a normal greensmower costs and you need 2-3X as many because they are electric and can only cover a few holes before they run out of juice. I'm sure they will get cheaper over time but right now the numbers don't work.
Automated spraying sounds like a terrible idea. Unless you're talking fertigation which has been in use for a while and seems to work pretty well. That said, I never hear of people retrofitting systems, only new installs, so maybe it's not that efficient. If it was, everyone would have done it by now.
Sensors in equipment seems like a good way to waste a supers time to watch what his guys are doing. If he's scheduling efficiently, has trained well, and has hired people who don't need micromanaging, he shouldn't need it.
