Nobody can work 100% of the time, everyone needs breaks. But some engineers take breaks from their regular work by doing other "work". I find it bizarre that there are so many comments making this out to be some kind of dire situation where he's working on other things because Tesla is sinking or something. Is working on hobby projects as a way to relax really that uncommon? For reference, I started a small Bitcoin mining hardware business back in the day, while still holding a 200/hr week/8 days a week/400 days a year full-time job. Working on Bitcoin stuff was my "break" from regular work.
