My idea is simple.
We have a lot of programming languages like c++, python and others. But they are not so phone friendly. So why not invent a new programming language adapted for smartphones or feature phones. With their small screens and slow typing keyboard.
The reason could be to teach programming to a bigger part of the world. Those who only have computer that is the phone. To be able to learn a little programming they probably don’t need to write super long code. However I think the knowledge of writing simple text based code could go a long way.
The phone is the most common computer. We should have a free and open source programming language system on it.
