I don't know what he is referring to. But one interesting things is that there is a language where you can express that someone is doing something without including the time when he is doing it. This is not possible in the languages I know of (De/En/Fr).

I can imagine that this ability makes different thoughts possible.

When looking at programming languages, it is indeed the case that your "lingua franca" limits the imagination of what software architectures are possible to solve the problem.

For a really eccentric example see:

Or just use of 無 in (ancient) Chinese for a simple example (in the sense of "unasking the question").
