Everything is easy though, humans can learn, I don't really believe anyone is so removed from potential that they couldn't learn to do any job at the average level of the average job's practitioner. Accessibility thus actually becomes the crucial differentiator. The opportunity to learn and be taught by the right people, to learn at the right pace and the right time, to be in a motivating environment, etc. So I think what people mean is... Yes programming is accessible, and there is good job prospect, and if you are worried you're not smart enough, that's crap, everyone is smart enough, just give it a shot. All you need is to be interested enough to put in the time and effort. Now you might not be interested enough, but compared to a lot of other things, programming costs you nothing to try. Same with mathematics, it's easy, but most people don't find it interesting enough to put in the time and effort. But mathematics is also less accessible, not as many blogs, free material isn't as available, there's no machine to freely assess you and grade your work, etc.
