I haven’t gotten time to dive deep, but I think that I would consider working on it, although I’m not convinced of anything just yet.
The reason I would consider working on it is because it is a field where youth can make great impact, unlike AI where a PHD is almost necessary to make impact.
The other thing is that you are potentially catching a wave when it is early, which can be very beneficial to your career.
Lastly, some of the people I respect most have started working on blockchain full-time, so that’s why I have a feeling there is something large there.
