It depends entirely on the race.
Races that can't get their act together on their own [Ogres, Orcs, Goblins] will resist right up until the point they're made slaves [or slave-equivalents]. Naturest races will try to seek out their own Enclaves where they try to keep everyone else out. Those that have their act together [I.e. Kobolds] would probably start to modernize almost immidiately.

And races that don't need to sleep will be seen like blessings for their ability to work 24/7.
