On the contrary. According to the article all the devices are essentially PASSIVE and REVERSIBLE. Including observers. Including the real ones, like you. It is just that any observers are unable to observe the erasure of their own memory, and thus are unable to observe the decrease of entropy (and reverse time flow). So you don't need to invent reversible quantum computers and simulate consciousness to get you answer, you are as reversible as these computers, and the time flows for you in both directions, but you (and any other observer) fundamentally unable to remember the reverse flow.Except few ARTIFICIAL examples, ALL realistic devices (inculding our brains) are significantly IRREVERSIBLE.
