Will artificial intelligence take our jobs? If you listen to Silicon Valley executives talking about the capabilities of today’s cutting edge AI systems, you might think the answer is “yes, and soon.”

But a new paper published by MIT researchers suggests automation in the workforce might happen slower than you think.

The researchers at MIT’s computer science and artificial intelligence laboratory studied not only whether AI was able to perform a task, but also whether it made economic sense for firms to replace humans performing those tasks in the wider context of the labor market.
