"80% of people can't do highly skilled jobs for obvious reasons.  I suspect artisan type of jobs will be the jobs of the future. "

That's exactly what I said, to retrain people to participate in the new economy; people don't become 'artisans' over night. Before sex robotics really become mature(could take another 2 decades or so),the 'jobs of future' that don't require much training is prostitution.

There're 2 kinds of people(I refer to yanks) most in needs IMO:

1)Those with jobs, not dyfunctional(at least not overtly) and willing to work but with declining future prospects, like truck driving and retailing.These people will be benefited by UBI, giving breathing space and retraining

2)Unemployed,dyfunctional, on drug or with crime record. Most of them are probably already on welfare, Free money on prolonged basis isn't the answer unless one wants to argue it from a different ideological angle.
