Ah yes, the standard tired "why Python sucks" tropes, as usual coming from someone who has made no attempt to improve the situation and barely understand the issues but feels they have the right to condemn those who are actually doing the work.
If you want C speed, use C. If you want C speed in Python, profile the bottlenecks and write them in C, the easy bridging of the two is one of Python's great strengths. Hell, Cython allows you to code pretty much pure python with type declaratives, which will run both as Python _and compile to C_.
There are more than enough solutions to the speed issues in Python. Unfortunately for you, they _do_ require you to do something other than whine about it.
