@akkartik If you're asking yourself if something is procrastination or learning, it's easy to ask yourself if you had been able to do this a week, a month ago.
But also, it's irrelevant.
It's relevant if you're trying to turn your weird play-computing into a business, or to save the world. But, if it makes you happy and not hurting anyone, I'd start digging to see if there isn't some other pressure telling you to not keep going.
You're allowed to dig into something if it makes you happy.
