Delphi was a pretty fun thing: nice IDE and nice language (would prefer c-style, but still c++ is much less friendly), but terrible licensing made it niche (VS had completely free, including commercial use Express edition + non-comercial Pro licenses for students while Delphi was few bags of gold for personal license for whatever reason making it completely irrelevant on a global scope, freemium is the way to go with stuff like this, this is the exact reason why windows and office are so easy to crack)
and you know, C sucks, c++ sucks, every language I ever heard of sucks
but the ones that get laughed at the most: JS and PHP seems to suck much less in terms of usability
but sure, lack of proper runtime/native compilers and GUI bindings make them niche (or used to, now unfortunately we have electron to make JS based GUI apps...)
