In the web programming world, we will still be trying to shoe horn fully-dessed circa-mid-90s client-server applications into documents-with-scripts-and-sockets. It will be necessary to know at least 17 languages to develop a modern HTML6 application.

Developers who are today children in primary school will be writing 70-character denunciations of node.js, which will be to be as old-fashioned as Ruby on Rails. This link-baiting intellectual dandruff, masquerading as deep thought, will constitute 100% of the HN front page.

Companies that sprung up to simplify Amazon Web Services will themselves become sufficiently complex that a new ecosystem of simplifier-simplifiers will spring up. You will be able to write code that runs at any one of the two dozen layers over cloud providers who layer over two hundred IaaS providers without modification. That's what the sticker will say, anyhow.

Github will have even more completely supplanted sourceforge. Good riddance.

99% of programming will be done in languages which are direct, legal descendants of the languages in which 99% of programming is done today.
