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.
