Well said
We have already shifted to open source development tools like Lowcoder, Frappe Framework, Noodl, etc.
Currently most of our development is for web only. We have successfully ported most of our enterprise apps to web.
For desktop apps we are currently exploring multiple ways. One that I personally like is the Electron route to building cross platform app using JS and HTML.
I am also maintaining an image processing software built in Delphi as it is not possible to port it to web.
