Artificial intelligence companies need our data. Can we stop giving it away for free?

Artificial intelligence is hot again, with everyone from Facebook to Amazon to Bill Gates talking about it at the 2016 Code Conference. But Bloomberg Beta partner James Cham, who has invested in several AI companies, says there are still a lot of unanswered questions about the field. "From our perspective, the dirty secret around machine learning right now is that nobody knows what they're doing," Cham said on the latest episode of Too Embarrassed to Ask, in conversation with host Kara Swisher and special guest host Mark Bergen. "Software is hard to write and machine learning is even harder to figure out. For a software developer to project-plan and figure out whether they're going to get results, no one has any idea."
