Then at some point, which could be just a few months or a few years or even decades later, you become wary of all the novelty. You only want to get involved in projects based on tried and tested methods. You start querying whether new technologies have proved themselves and whether they represent an advance. That's the time when you get alienated by the commercial pressures that interfere with the pure enjoyment of coding. I'm talking about the switch from when writing software gives you a buzz, a sort of high, to when it just becomes a job.
Some developers become journalists.
I'm not the only one. In journalism you can still have the buzz given by the creative act of writing. Of course, you are close to 'news' all the time, and in the technical press you preview new technologies regularly. In a way, it is very frustrating. Most of the languages mentioned above are now just happy memories.
