Security robots are being used in San Francisco to drive away homeless people.

Aside from the cruelty of driving them away without making a place for them to go, these robots will make more homeless people by replacing human security guards.

Providing services that have to be done in a particular locality is the last source of employment for most Americans, so if we allow these jobs to be automated, we will predictably get a lot more homeless people. We need laws to limit the robots' use so as to protect the jobs.
