You aren't alone. My professional written communication is meticulous. I think carefully about my audience and optimize word choice for very low probability of accidental collision or misinterpretation.
I don't think everyone should communicate this way all the time, but I do think everyone should recognize that loose communication in mixed company can waste a lot of time. My job involves inter-team and inter-department collaboration and I take the time to do it well.

I agree AI is eroding diction. I don't like the idea of such a heavy inertial force on the evolution and usage of language. Or the idea that it might be grinding off variation in word choice and self-expression.
I think there are bigger negative impacts here than most people realize. For example, it reminds me of the part in Snowcrash about how language variation is important to mitigate the spread and criticality of mind viruses and danger memes. I think you could totally look at modern authoritarianism through this lens, for example.
