Do you want to build new software? If yes, look elsewhere.
Do you want to maintain or port old small business software and possibly make large sums of money? Then it might be worth learning Delphi.
Otherwise, Delphi is dead. But I do know of at least one programmer (albeit with excellent personal marketing skills) who learned RPG and became a multi-millionaire taking RPG contracts long after it was considered "obsolete".
I know a couple of Delphi developers; good developers. I don't think that they would recommend learning the language today because the number of legacy systems still in Delphi are declining, few new projects use Delphi, and while there are web frameworks, app development frameworks, etc., they really only exist to help existing developers and are not remarkable enough to be worth learning the language.
I think it is objectively hard to measure this sorta stuff, but considering there are 2,139 jobs listed using an aggregating job search engine for delphi. Compare to most of the other language and you find many many many more jobs.
so by that measure, yes. By another measure, maybe not.
