This is exactly my experience. Because the barrier to doing things is lower, you just do more things. But it doesn't actually expand one's capabilities or make learning happen any faster. That needs time (mostly sleep).

Compare playing Counter Strike with having a game of cricket.

Cricket takes a while to organise and set up. You have to contact your pals, physically travel to the field and set up the wickets. Then expect to commit several hours to the game.

Meanwhile, Counter Strike takes no effort. You move your arm to the mouse and click. A game is like 5 minutes of commitment.

The trouble is, before you know it you've spent 5 hours on Counter Strike. You could have easily played cricket in that time, caught up with your pals and exercised your body to boot.
