entanglement
About five years ago I sent this email to Erik Verlinde:

Dear Professor Verlinde,
I read your preprint about gravity as 'entropic force' and have the following question/suggestion:
It seems that there are large classes of systems following an area law for entanglement entropy, see e.g. arxiv.org/abs/0808.3773
Should they all show 'entropic gravity' somehow?
If yes, the obvious next step would be to pick a simple model, e.g. arxiv.org/abs/quant-ph/0605112 and check if/how entropic gravity manifests itself.
Thank you,
Wolfgang

As it turns out this idea may not have been so stupid after all.
Of course, if entanglement stitches space-time together then the question remains: entanglement of what?
I still think the entangled qubits of a quantum computer are the most natural candidates; if we live inside one it would also solve the measurement problem.
But what would it be computing? We can only speculate.

Does "Hotel California" supports purposeful computations at all or is it more hellish to stack on a non-halting one? What if it also deprives all its inmates of any previous memory immediately after check-in? It seems Philip Dick has told us everything it could be said on such matters already.
