> But otherwise I think it's harmful to society, even if beneficial to the individuals

I disagree a little in that stability/predictability to people also adds some benefit to society - constant disruption/change for the sake of efficiency I believe at extreme levels would be bad for mental health at the very least and probably cause some level of outrage and dysfunction. I know as an SWE tbh I'm feeling a bit of it - can't imagine if it was everyone.

I personally think there is a tradeoff; people on average have limits to adaptability in their lifetimes and so it needs to be worth it for people to invest and enter in a given profession (some level of economic profit that makes their limited time worth spending in it). It shouldn't be excessive though - it should be where both client and producer get fair/equal value for the time/effort they both need to put in.
