They did a Java BASIC language Jabaco to work like VB6 and compile to Java files. https://www.jabaco.org/ I think someone should take it over and remove the technical debt.
What don't I like about modern .NET. well I just don't like .NET. it's massive, the tools are confusing, etc. F# is the only language I actually enjoy there and it's just not great performance wise. I can write C# fine, but I don't like it.
Give me a rust RAD that runs cross platform. Make sure it has an easy way to draw to canvases or good chart/drawing libraries. I'd pay real money for that. I hate fiddling with front end but I hate not having a decent one more when visuals matter. Fine it could be Go or modern c++, I don't care that much but please no .NET
