> it probably has more exceptions and weirdness than english.
Pronunciation-wise, I doubt it. All your examples have English counterparts.
Consider eleven (the vowel sounds for the same letter), psychology (silent p), wind / rewind, many irregular verbs (like read, read, read), Wednesday and business (many letters are just not/weirdly pronounced), history and litterature (one fewer syllable than expected), the complex rules to pronounce the ed + exceptions... You basically have to know how an English word is pronounced to pronounce it correctly. Guessing works but only so far, and I believe less than for French (and I'm a French speaker too).
I have a close friend from the US who likes to make fun of the French language, but when I cite English, he says oh yeah, but for English we already know that! :-)
Anyway, English and French are both quite bad at this, and you are right, that's nothing to be proud about. It's just a reality we have to deal with.
> The language is becoming simpler and simpler, dumber and dumber.
Simpler is not dumber and I absolutely don't think the language is becoming dumber. The last reform (1990) brings more regularity and this is most welcome, freeing us time for things that actually matter, making the language more accessible to foreigners as well as people with conditions like dyslexia or dysorthography and less a status tool. I welcome the French language becoming more welcoming.
Or please strongly back your dumber and dumber statement. Because usually that's just baseless, tired rambling from clueless conservative people saying such things. A French speciality (a national sport even, championed by the Figaro?).
> And you probably don't want to get me started on the average reading and writing skills in elementary and secondary schools in France. It's in freefall
That too. Maybe you should fix your English before lamenting on the writing skills of people, because you are making a lot of basic language mistakes in this very comment in which you are doing this. That's harsh and not nice, but that's what you are seemingly doing to others and I want to take the opportunity to make you feel what it may feel like. Actually, you probably cannot even begin to imagine how you may sound like to people for whom writing is a struggle. Such people often feel ashamed because of people like you. Let's just be forgiving, tolerant, more empathetic and stop using language skills as status and start focusing on the content.
I have a close acquaintance who expresses themself perfectly, only writing without mistakes is hard for them. They even have an official disability recognition for their strong dyslexia (so they can have a related tool on their workstation). Let's just cut people some slack on their writing skills (which are in the vast majority not related to laziness - or maybe you are suggesting people are dumber and dumber?) and the world will be a better place.
See also [1] for a nuanced discussion on "Writing skills are lower and lower". It turns out it's partly due to more people going to school and not only the elite, which is a good thing, including children whose first language is not French and whose life in general may likely be a bit more complicated than the one of a random privileged French child (like I was).
