So, Assuming his tweet wasn't merely a publicity stunt - what was it about? Is the fact that he put out a call for coders indicative of the type of challenge he's facing with Autopilot? I wonder if it means the issues are translating AI concepts into efficient code, rather than solving the AI problems themselves. Just got me thinking because the tweet was really non-specific - it didn't call for machine learning experts, machine vision experts or anything else - just "hardcore" coders. Seems a bit odd.
