1. Languages will evolve to make as short as possible in terms of lines of code. Shorter syntaxes all the way.
2. Each platform/part of architecture will have only 1-2 languages to code in. There will be convergence of languages. This is more to do with industry usage. Underground new languages will still continue to flourish.
3. Focus will be more on natural language. Both as research item for understanding humann languages better and possible movement of coding languages in the direction of natural languages. Natural syntax as much as possible.
4. Softwares will be self learning. Every interaction will result in the software to evolve as per your usage. That would mean the same software will behave differently for every user. This will be basis user's interaction.
5. Less physical interaction. More to do with what the user thinks. Intuitive.
