My speculation: perhaps JW Dunne’s Serial Time is our human perception of non-temporality. And it is interesting to compare Dunne’s idea with those of Rovelli (q.v.) that posit non-temporality as the norm, with only our brains creating our 'before-and-after' view of time that only works in the surrounding locations near (on an astronomical scale) to us.
The Quanta article also mentions some possible implications for quantum computing, notably that:
Quantum computers are sometimes described as performing a series of operations on all possible data at once, but they might also be able to perform all possible operations at once.
Incidentally, Quanta is free (no advertising, and funded by the Simons Foundation) and well worth ‘subscribing’ to.
