a “time machine” that moves an electron back a microsecond is at least energetically within bounds of near-term technology.
Do you have a pointer for this? Traversable wormholes tend to require massive amounts of energy[1] (as in, amounts of energy that are easier to state in c^2 units).
There is some reason to believe that an outcome pump with a sufficiently short time horizon is easier to safely get hypercompute out of than an AGI, and that a “time machine” that moves an electron back a microsecond [...]
Note: this isn’t strictly hypercompute. Finite speed of light means that you can only address a finite number of bits within a fixed time, and your critical path is limited by the timescale of the CTC.
That being said, figuring out the final state of a 1TB-state-vector[2] FSM would itself be very useful. Just not strictly hypercomputation.

Or negative energy density. Or massive amounts of negative energy density.
Ballpark. Roundtrip to 1TB of RAM in 1us is doable.
