…is that anyone can learn how to do it.
You don’t need a lot of money, a degree, or a team of people. All you need is a computer and the desire to learn.
The internet makes is very easy to share things with others, get feedback and improve. Every iteration takes your product and your skills to the next level.
In addition, it’s very easy to see if the feature you are working on is functioning properly. If you are working on a web app, sometimes all you need to do is reload the page (or better yet, automate it by writing a test).
Learning programming (and many other things) has never been easier. If you have never done it before, try it, even if you don’t plan on doing it professionally.
And if you are an experienced programmer, spend some time teaching others or building something cool just for fun.
