It'd be interesting to see how big a CPU chip scaled up to be big enough for a human to fit in (were it hollowed out) would end up being.

Reminds me of the Monster 6502. Not quite what you're suggesting, but still a large discrete monster of a board.

Instead of a hedge maze maybe we can have VR "walking through a 8086 or 8088" chip style maze in the future.

Not a whole chip, but an important section of one:

They're usually 150μm thick. Humans fit in about 300mm thick spaces, so you need 2000x linear scale.

Not to answer your question exactly but ...

Chips seem to be around 25mm sq, and the smallest features around 10nm. If you scaled up so the smallest feature is one mm then the chip would be around 2.5km square. (over 1.5 miles on each side)

If the smallest feature was about the width of human hair then divide the above by 100.
