a) basic income, or
b) all the unemployed who can not get a job in the new economy are given a government job. The work in the job doesn't matter, as long as it provides a fig leaf to allow the government to give them the money they desperately need to live.
If its not entirely clear, I think that these non-jobs are are an unfair and incredibly expensive way of giving out benefits. The richer would be better off with a basic income (free money! smaller more efficient government meaning taxing the rich less!). The poor would be better off with a basic income (no social workers or benefit admins judging you! future is predictable so able to start investing for the future!). Its only annoying for those of us in the middle, those who will not benefit much from a basic income (because it won't be a huge amount of money, our taxes are unlikely to decrease) but will also not see much benefit from it (I probably already had a safety net in terms of friends and family, and the basic income will be too small to support the lifestyle I am used to anyway).
