I spent two decades as a Delphi contractor. Not doing it anymore, but I still see a lot of control software for industrial machinery and lab equipment (at least those made in EU), POS and kiosk software as well as custom ERP and ERP style software.

I am currently working on NIR spectrometer and I am actually thinking about using Lazarus for driving touch screen instead of web based dashboard.

For example this company uses Delphi on their software products,

In Germany, there are still conferences with Delphi contents (EKON 24 and BASTA), and some magazines have occasional Delphi content.

A lot of medical software was written in Delphi and still going - it was written by Doctors and grew.
