Yeah, Mathematica is basically MACSYMA on steroids. Wolfram is indubitably a genius, and he took it far past what the general research community and even the Lisp research community did. But I can't blame him for choosing to become a billionaire rather than a vulnerable and derided eccentric like RMS. I hope he chooses to share his work after his death.

I totally agree . Mathematica is not just macsyma on steroids its like the Java of symbolic computation. He is literally putting every kind of scientific and or mathematic concept and adding it to the language.
