There's a lot a legacy application written in Delphi here. Some old programmers, that only know to program in Delphi, may even build new apps with it.
It may not be that modern today, but there's the "pay the bills" mindset.
I think Delphi will die, but only because it costs a fortune today. If it had a resonable price, many people would continue to use it indeterminately.
