I do agree with you. We have an natural eye (what you call a 'biological brain') automat that inconsciouly 'feels' the structure of a geometric of the places we enter to.

Once this layer of "natural eye automat" is programmed behind a camera, it will spit out this crude geometry : the Spacial-data-bulk (SDB). This SDB is small data.

From now on, our programs will only do reason, not on data froms camera(s) but only on this small SBD.

This is how I see it.

==> And now the LLMs, to feel Spacial knowledge, will have a very reduce dataset. This will make spacial data reasoning very less intencive than we can't imagine.
