San Francisco — Security guard Eric Leon watches the Knightscope K5 security robot as it glides through the mall, charming shoppers with its blinking blue and white lights. The brawny automaton records video and sounds alerts. According to its maker, it deters mischief just by making the rounds.

Leon, the all-too-human guard, feels pretty sure that the robot will someday take his job.

“He doesn’t complain,” Leon says. “He’s quiet. No lunch break. He’s starting exactly at 10.”

Even in the technology hotbed stretching from Silicon Valley to San Francisco, a security robot can captivate passers-by. But the K5 is only one of a growing menagerie of automated novelties in a region where you can eat a delivered pizza made via automation and drink beers at a bar served by an airborne robot. This summer, the San Francisco Chronicle published a tech tourism guide listing a dozen or so places where tourists can observe robots and automation in action.

Yet, San Francisco is also where workers were the first to embrace mandatory sick leave and fully paid parental leave. Voters approved a $15 hourly minimum wage in 2014, a requirement that Gov. Jerry Brown signed into law for the entire state in 2016. And now one official is pushing a statewide “tax” on robots that automate jobs and put people out of work.

It’s too soon to say if the effort will prevail, let alone whether less-progressive jurisdictions might follow suit. The tussle points to the tensions that can flare when people embrace both technological innovation and a strong brand of social consciousness.

Such frictions seem destined to escalate as automation makes further inroads into the workplace. One city supervisor, Norman Yee, has proposed barring food delivery robots from city streets, arguing that public sidewalks should be solely for people.

“I’m a people person,” Yee says, “so I tend to err on the side of things that should be beneficial and safe for people.”

Jane Kim, the city supervisor who is pushing the robot tax, says it’s important to think now about how people will earn a living as more U.S. jobs are lost to automation. After speaking with experts on the subject, she decided to launch a statewide campaign with the hope of bringing revenue-raising ideas to the state legislature or directly to voters.

“I really do think automation is going to be one of the biggest issues around income inequality,” Kim says.

It makes sense, she adds, that the city at the center of tech disruption take up the charge to manage that disruption.

“It’s not inherently a bad thing, but it will concentrate wealth, and it’s going to drive further inequity if you don’t prepare for it now,” she says.

“Preposterous” is what William Santana Li, CEO of security robot maker Knightscope calls the supervisor’s idea. His company created the K5 robot monitoring the Westfield Valley Fair mall in San Jose.

The private security industry, Li says, suffers from high turnover and low pay. As he sees it, having robots handle menial tasks allows human guards to assume greater responsibilities — like managing a platoon of K5 robots.

Li acknowledges that such jobs would require further training and some technological know-how. But he says people ultimately stand to benefit. Besides, Li says, it’s wrong to think that robots are intended to take people’s jobs.

“We’re working on 160 contracts right now, and I can maybe name two that are literally talking about, ‘How can I get rid of that particular human position?’ ”

The question of whether — or how quickly — workers will be displaced by automation ignites fierce debate. It’s enough to worry Microsoft co-founder Bill Gates, who suggested in an earlier interview a robot tax as a way to slow the speed of automation and give people time to prepare.

A report last year from the Organization for Economic Cooperation and Development concluded that 9 percent of jobs in the United States — or about 13 million — could be automated.
