>full dive VR requires molecular nanotechnology

I don't think so. FDVR only requires three things:

Isolated brain kept alive via artificial vascular system feeding it nutrients and essential chemicals. Has already been done in pig brains kept alive 36h in 2019, if I am not misremembering.
Connection with sensory nerves that send and receive signals. There are already rudimentary technologies around this, mostly targeting prosthesis control and sensory implants.
AI world generators.

Molecular nanotech will make it easier, but is not strictly necessary.

This is feasible but it wouldn't be necessary with a technology (such as molecular nanotechnology for instance) that could alter a person's internal clock to make a million subjective years occur over the course of a single objective day.
There are many senses beyond sight, smell, taste, touch and hearing (such as depth, distance, equilibrioception, kinesthesia, thermoception, etc.) that would have to be perfectly simulated; how much bandwidth would be required for flawlessly simulating them all and how long would it take?
AI creating worlds is definitely possible without molecular nanotechnology.

That's not good. You are much more likely to change someone for the better or worst. Change is not always for the better. Just have one second be in real time.
