Well, that is changing because technology now allows us to communicate with each other from distant locations. There are websites like HackHands where you can code with a mentor simultaneously. So even the "loneliness" barrier to coding is also dissolving.
I disagree. Although that technology is wonderful, you will still always need the kind the drive and determination to do figure things out for yourself.
It's one thing being shown how to do something, it's another thing to work it out for yourself, in much the same way as studying maths or physic etc.
No doubt, but that is then true about nearly anything - art, music, film, photography. At the end of the day, we are all alone, but that isn't an excuse to dissuade you from doing anything, especially not coding.
