My AI program can only use 4GB of RAM in pypy. How much in CAD would you need to implement the 64 bit solution?

Pypy has made my code so fast, that C++ is possibly not worth writing in ATM.

This works fine for me on a 16 Gig system:
/usr/local/pypy3-7.3.3/bin/pypy3 -c 's = "a" * 2**33'

Is it possible you're using a 32 bit build of pypy?
