In a not-too-distant future city, superintelligent robots will carry out the majority of vital tasks. Driverless cars will ferry passengers to and from points of interest. Housing and healthcare will be affordable, if not free to all. Political leaders and technologists will speak the same language. And life is good.

Sam Altman, the 32-year-old president of Y Combinator, the most prestigious startup accelerator in Silicon Valley, has laid out this utopian vision over the years, and most definitively in a job listing posted on YC’s blog in June 2016.

“We’re seriously interested in building new cities and we think we know how to finance it if everything else makes sense,” the post read. “We need people with strong interests and bold ideas in architecture, ecology, economics, politics, technology, urban planning, and much more.”
