The bit I don't get is not that they might get hotter, they may, it's more to do with where and how you ride something. I don't get why some people seem to think that they will constantly be too hot all the time as they roll to the end of their driveway. They seem to have heard that it's possible that they overheat and think that's a reason to avoid them like the plague. People used to overheat MTB brakes more as they were shitter, and even then it was just one or two people on really long, brake heavy descents. The brakes are now a load better at getting rid of heat to the point that it's pretty hard to overdo it unless you set out to on purpose, your disc brakes will almost certainly not overheat.
