I'm absolutely with both of you, but I'd like to point out that non-native speakers often tread a very fine line. They need to fear sounding either too convoluted or a bit of a simpleton. Proficiency levels vary wildly, and not everybody in the audience is as receptive and welcoming to slight mistakes as you are, even tough I have to admit HN in particular is pretty tolerant.

I for one don't think I'll ever AI-wash my texts or use AI translations verbatim. If everybody else did, it would certainly be a sad loss of diversity, but IMO it's only going to make the people who put in their own effort stand out more. Hopefully in a positive way. Time will tell if we're a dying breed.

I'm afraid the need for anybody to learn foreign languages will be subject to much change and discussion for upcoming generations.
