> I mean, think about it, when you finally understand a math problem and get that AHA-moment, this is the biggest hit of dopamin you can ever imagine, no?

Not really, but I do get that when I've completed a challenging project. I love learning and engage in it constantly, but it's never given me a dopamine hit.

> the biggest difference between being addicted to learning vs. social media is the delay of gratification.

That may be a factor, but I really do think the largest difference is being mentally passive vs mentally active. Social media requires no effort. You let it wash over you. It's the same as television: mental candy, empty calories. Learning requires mental effort. It's like a full meal.

All that said, people vary a lot on this sort of thing and so a tool like this may be very useful to many.
