- Top 4 languages are going down (Java, C, C++, C#)
- Delphi is now significantly more than 50% the size of Microsoft C#
- R is going up, fast
Will Delphi overtake C# and Microsoft .net? Maybe - Delphi works on mobile phones, but Microsoft .net doesn't.
My personal opinion is, that you should pick the development framework that suits your needs, with regard to productivity, legal issues, tool-supplier support, longevity expectations, deployment options etc.
