Runtime inefficiencies are no excuse to use a lower level language - if I had a language that let me write a 2d platformer game in 3 days but pushed every player's computer to their limit, I would use it.
In addition, considering there's languages out there with much, much greater runtime inefficiencies of languages like python being used in the client/server side of massively complex games like Eve Online, there's a lot more that should be taken into consideration when choosing a language other than raw speed.
