Clearly if it will be 53x faster in 32 years even if written in C,
then it should be rewritten in Python for another 53x speedup!

Imagine the possibilities.  You could even implement another virtual
machine underneath the current one, to increase speed even more,
provided *that* one was executing Python bytecode as well.  Scary
really.  I understand this plan was discussed at a recent PSU mee
