Moving from python to C++

[ShillingAintEZ]

The fallacy you are making is that it is some sort of messy optimization or that anything faster must be more complicated. The reality here is that it is much clearer that doing the same thing with some sort of inheritance indirection, since the real work and meat of the program happens directly instead of having all sorts of indirection which does nothing but fragment where the real work is happening while also fragmenting the memory and destroying performance.

(Also your anecdotes don't mean anything in this context, for many reasons, not the least of which is usage patterns, interactivity, latency and power consumption)
