Isn't the same guy behind both Delphi and C#? Anders Hjelsberg if memory serves.
TP and Delphi, obviously, require no apologies.
And yes, the language itself is a joy to code in. Which is opinion, not fact, I realize that.
And C++ powers Google, Facebook, 100% of AAA games, 90% of mainstream OSes, and 90% of all top-of-the-line commercial programs (from browsers and office apps, to Photoshop and AutoCAD).
Nothing to apologize about RoR either.
No need to apology for them.
