The problem with a very slow transition, or one where people don't even pay attention is for the people that are affected directly by it. You don't care if your neighbour is unemployed because you got yours.

They will have to try and study a new career path for a couple years or start from the bottom of a trade. All while being unsure if their next career of choose will disappear before they advance at all.

A quick instantaneous one would be amazing, but extremely unlikely.

I'm not sure which end of the spectrum it will be, by my fingers are crossed for quick enough to reduce suffering for as many as possible.
