That comparison seems quite cherry picked. Unlikely that it is generalizable. In my tests with Mojo, it doesn’t seem to behave like Python at all so far. Once they add the dynamism necessary we can see where they land. I’m still optimistic (mostly since Python has absolute garage performance and there’s low hanging fruit) but it’s no panacea. I feel their bet is not to have to run Python as is but have Python developers travel some distance and adapt to some constraints. They just need enough momentum to make that transition happen but it’s a transition to a distinct language, not a Python implementation. Sort of what Hack is to PHP.
