Of all fatuous nonsenses I've heard from design "geniuses" over the years, that might take the prize.

We don't look at spoken words, we listen to them. We add audible prosody (both pauses and intonation changes, in particular) to segment our speech. If we were to optimise our spoken language for lip-readers, we might very well choose to add some extra visible segmentation to compensate for the intonation being mostly undetectable.

You could validly claim that capital letters are superfluous given the presence of full stops (and I would disagree and we could debate that), but this argument that capital letters are bad because we don't speak "big sounds" is absurd.

We don't speak big sounds? We also don't speak commas and full stops, but those are still an important part of writing. Trying to get some of the suprasegmental features of speech into low bandwidth text.

Yes, let us write without spaces or punctuation, that is what we used to do always!
