> I know Delphi!
I would argue you can made good courses in any language and it would seem more convenient to teach in something that has better transferrability into industry.
Also the response is likely aggravated by this quote from the source article:
> a curriculum that has taken heavy damage from the adoption of Java and C# in the early 2K’s.
wut?
As an example, the free version of Turbo C++ 1.01 that is available through the Borland/Embarcadero museum (or was at some point, i don't know if still is) has ~34 introduction examples (referenced via their guide) that outside of a couple, use only basic stdio and stdlib stuff (these 2-3 examples that use a non-standard header use conio.h which AFAIK is borland specific, though Watcom/OpenWatcom and Visual C++ also seem to provide the used functions) without any DOS-specific functionality (be it far pointers or whatever) and could compile with any modern compiler.
