This is true to a point. But eventually, you've gotten all you can from learning and managing a new thing. You can't reasonably make it more efficient and there are no benefits to spending more time learning it. This is when it shifts from a hobbyist's exploration to a routine, mundane task that requires time and attention while offering no _new_ benefit.

For some hobbyists there's comfort in this repetition; for others, it's just a time sink with high opportunity cost.
