Speaking of Forth... Here's a fun bit of trivia.

PowerPC and Intel Macs used to use Open Firmware[0] to define their firmware (BIOS). Macs with M1[1] architectures and subsequent generations may also, but I cannot attest to this.

For those Macs which do use Open Firmware[0], a key implementation component of it is FCode[2]:

  FCode is a Forth dialect compliant to ANS Forth, that is 
  available in two different forms: source and bytecode. 
  FCode bytecode is the compiled form of FCode source.

So if anyone asks, "who uses Forth anymore?", a correct answer is - a large percentage of everyday people.
