The language is not dumb. The writing system that people chose is...not that great (and you can call it dumb if you like). There was a choice between respecting phonetics or maximizing some other objective (respecting etymology or being consistent with older pronunciation or whatever). Being based on a latin script maybe wasn't ideal, but languages like swedish or german did a better job and invented letter when needed.

If you take the distribution of writing systems, I'm not sure English is particularly bad (the modern version has spaces and punctuation! Not bad, right?). It's not great either.
