What kind of evidence do you want? I wrote Delphi for years and I'm now a Typescript developer. Is there any current major software written in Delphi?
The most important ones I found are the windows MySQL GUI, Cheat Engine and Total Commander. I genuinely was searching for more than 10 minutes and everything else is either abandonware or has been rewritten to a different language.

That is not evidence for "no reason to exist".
The major reason for Delphi and/or Lazarus and/or Qt and/or similar WYSIWYG tool to exist is "when you want to produce a cross platform GUI application using a drag-and-drop form builder."
The fact that I can write a chat application that uses 30MB of RAM at runtime instead of 800MB like electron does is just icing on the cake.
