I feel like both could seem true depending on the lens of the observer. I've had projects where I feel like I'm cruising to the point of boredom and other projects where it does feel like long work hours. I don't know if I agree with the less social part either, a lot of devs I know are quite social in distinct ways(board games, video games, technical groups, etc...)!

Depends on the job and the industry I guess. I’ve normally had to do 50-60 hours on a salary unless I’ve ran out of upward mobility at a company & just want to coast for a few months until I find something else
