You don't, it's all opinion, but that doesn't mean it doesn't exist.

We can at least all agree there is difference in the efficiency of writing a program in binary opcodes for a specific architecture vs writing one in C... although quantifying it is impossible, and that's just one quality.

Leaving the low level languages aside, most of the top level one can achieve the same things with similar costs. It's still up to the individual/team skill how those apps/systems end up to be built. If some project fails, is rarely "picking the wrong language" reason...
