"Blue collar workers and service industry workers aren't in immediate danger of being replaced by AI"

I wouldn't be so sure about this; robotics is advancing rapidly. I do think there'll be a substantial market for "human-made" products and services as luxuries, though, so at least some humans will retain these jobs.

Blue collar workers such as plumbers are in danger of being replaced by robots, but not any time soon. But by the time this happens, enough people from more vulnerable fields will have been forced out that a "solution" will have been found. The "solution" is much more likely to be dystopic than utopic though.

I'll believe that when I can get a robot plumber or electrician to come to my house for less than what a senior SWE makes per hour. Until then, it's just an empty promise.
