What language cavemen could program in?

C/C++ syntax is quite unforgiving for mistakes, and cavemen weren't good abstract thinkers.
I think something like a variant of LISP or Forth could be used to teach a cavemen basic programming.
Haskell or restricted subset of it, would look like pseudocode and could be more palatable to primitive cavemen

"A few groups of elites" are ensuring their own material wealth, not your technological progress. The richest 1% now has as much money as the rest of 99% - that's a success. Technology? Nobody cares. That's why people are still using languages that are beaten by PLs from the 60ies.
