Its not the case because its unlikely that the technology will be adopted everywhere, simultaneously, overnight; it will be adopted gradually over time; it'll probably first manifest in the job market as a decline in growth in trucking jobs, then a decline in trucking jobs, rather than going from the existing pattern one day to no humans working as truckers the next.
I certainly won't be overnight. But you are assuming current truck drivers will have time to migrate to new jobs as those appear - I really doubt two decades is "gradual" by that measure. Yet, I can not see how it could take that long.

No, and I'm not even assuming that new jobs will appear.
That there will be warning and that there will be much that can be done with the warning are very different ideas; OTOH...

Two decades is enough time for people who are mid- (and often even early, though not quite at the beginning) of a career to retire and not need to worry about a new job, so its potentially gradual enough.
