I worked with Delphi personally and professionally for many, many years. You were at the precipice of unemployment in the 2000s if you used it then. To do it now? You're like a looney toons character suspended in mid-air. There's Delphi work around, to be sure, but you're competing against people with 30 years of commercial experience building -- or rather just keeping them limping along -- today, and they are as desperate as the Powerbuilder, Oracle Forms, FoxPro and Lotus Domino folk in scratching out an income in a stagnant pool.
Delphi died an ignominious death a long time ago, and it is truly sad. I miss it; frontend development today is a joke compared to what we could do with Delphi. But so what? It's dead. And it's not coming back.
Yeah, Delphi is not in the top 5, but is clearly very far from dead. Especially in comparison to the untold number of languages and companies out there.
Object Pascal can also be transpiled into other languages, where people are not aware of what the original code was written in. For instance, Russia makes wide usage of PascalABC, which compiles/uses .NET. There is also Oxygene (RemObjects), that can compile to .NET too.
Popularity and usage does not equate exactly to the job market. For instance Scratch is more popular and widely used than Rust, because of its reach with the young and schools. And, many jobs can ask for programming skills, like knowing Python (which boosts its ranking). But they are often asking for that language as a supplement or plus, not as the main reason why they are hiring a person.

Genuinely asking, not trying to be snarky. My prior assumption is typically that a capable engineer in one language or stack can learn another relatively easily.
why?
