Is there any evidence that this really matters on top of the protections and limits that are already built in and obscured from the user? There’s such a cult around this feature, but I’m not convinced.

I don’t think so, my point was that there’s not only uncertainty in converting the idea to language and language back to an idea, but there’s also uncertainty when transferring language from one person to another.

There’s also the difference between what you think the words you say mean and what they understand from your words.

I don’t know about La Guardia but Heathrow is definitely at its capacity limit due to only having two runways.
