I compare it to trying to learn a musical instrument: - most people can learn to some degree - hard work and dedication can compensate for a lack of ability - for those of little talent, their end-point ability will always be very limited - the truly talented can make mastery of their instrument look truly supernatural

As not all people should be musicians professionally, not all people should be programmers professionally. It's hard to put my finger on it, but in both cases some people just don't 'get it'.

Of course, if you are talking about having fun on your own - writing apps or making music - or 'jamming' code or music with your friends - you can do whatever you like.
