Last time checked, Delphi (Object Pascal) is ranked #10 on the TIOBE index (August 2025). People get all hot and bothered by Rust and others, yet they are still way behind on the charts.
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.
Delphi/Object Pascal is taught in many places around the world and its usage depends on the country. Because Delphi/Object Pascal is not so popular in your or a specific country, does not mean its not more popular somewhere else. More people and companies use Delphi than many realize, that's why they are still in business.
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.
