The resistance to "killing off" VB6 is in large part based on there being nothing as good to replace it. Unless you're willing to pay thousands for a Delphi licence, your only options are:

1. Modern .NET for desktop apps, whose many semi-obsolete UI frameworks make Java's UI tools look simple

2. Learning HTML/JS/React/Redux/CSS/Bootstrap/Python/Django/SQL/SQLAlchemy/Webpack...

Neither is likely to appeal to someone used to how easily applications could be created in VB6 or Delphi.

(I believe this so strongly I cofounded https://anvil.works, which is basically VB6/Delphi for the web. That's not so much a disclaimer, I guess, as putting my money where my mouth is :-P)
