I think a good model for UBI would be to pay anyone who is currently in school-- students and teachers. And, concurrently, make public universities tuition free for most if not all people.

1) Unemployed people would choose to go to school to collect UBI. They'd acquire skills that could get them to a point where they can perform high-skill jobs, and would choose to re-enter the work force when they graduate because they'd stand to make much more money than they would staying in school and earning UBI, since they now qualify for high-skill, high-pay jobs.

2) It would directly work to counter-act the affects of industries dissolving from automation and obsolescence. People laid-off could seek education for retraining.

3) Young people would choose to stay in school longer, and shoot for higher-levels of education, leading to a smarter populace and a larger automation-proof workforce.
