A machine learning learning PhD doesn't only open up some of the highest-paying jobs around, it sets you up to have an outsized positive impact on the world. This comprehensive guide on machine learning PhDs from 80,000 Hours (YC S15) will help you get started. The guide is based on discussion with six machine learning researchers including two at DeepMind, one at OpenAI, and one running a robotics start-up. Check out the highlights below. Machine learning involves giving software rules to learn from experience rather than directly programming the steps it takes.

Twitter (NYSE:TWTR) recently acquired Magic Pony technologies, a machine learning startup focusing on deep learning in computer vision. In my continuing coverage of the AI market, I want to briefly comment on this transaction. First, another contributor has already commented and described the company's product (without technical details). At its core, Magic Pony uses machine learning to enhance low resolution images and videos. It is quite remarkable when you think about it.
