Yes, but it thankfully for me only lasted a couple of hours and they didn't start keeping track until near the end.

I had a very similar experience as a teenager after a mild concussion from falling on ice. According to my family, I would 'reboot' every few minutes and ask the same few questions exactly. It got burdensome enough that they put up a note on the inside of my bedroom door with something along the lines of:
"You are having amnesia"
"You hit your head and got a mild concussion"
"You've already been to the ER, they said you're likely to be fine after a few hours and it is safe to sleep."

The entire experience was (reportedly) very stressful to me due to disorientation.

Yes.

For example: The common saying, "Anything worth doing is worth doing [well/poorly]" needs more qualifiers. As it is, the opposite respective advice can often be just as useful. I.E. not very.

Better V1: "The cost/utility ratio of beneficial actions at minimum cost are often less favorable than they would be with greater investment."

Better V2: "If an action is beneficial, a flawed attempt may be preferable to none at all."

However, these are too wordy to be pithy and in pop culture transmission accuracy is generally sacrificed in favor of catchiness.

Yeah, many people, like the majority of users on this forum, have decided to not build AGI.

Not to build AGI yet. 
Many of us would love to build it as soon as we can be confident we have a realistic and mature plan for alignment, but that's a problem that's so absurdly challenging that even if aliens landed tomorrow and handed us the "secret to Friendly AI", we would have a hell of a time trying to validate that it actually was the real thing.

If one is faced with a math problem where you could be staring at the answer and know no way to unambiguously verify said answer, you are likely not capable of solving the problem until you somehow close the inferential distance separating you from understanding. Assuming the problem is solvable at all.

Yes, thanks!

What would the minimal digital representation of a human brain & by extension memories/personality look like?

I am not a subject matter expert. This is armchair speculation and conjecture, the actual reality of which I expect to be orders of magnitude more complicated than my ignorant model.

The minimal physical representation is obviously the brain itself, but to losslessly store every last bit of information —IE exact particle configurations— as accurately as it is possible to measure is both nigh-unto-impossible and likely unnecessary considering the moment-to-moment changes living causes to the particles, while "self" appears constant.
So would the detailed information of cell positions and compositions be sufficient granularity? How practical would it be? I don't know of any existing technology that is able to achieve the level of detail that would likely be required. MRI is very impressive, but while structure can be viewed (at least down to a 0.2mm resolution as of 2024-04-02), chemical composition cannot (as far as I know). 

Do we know what the important variables are, and do we know what tolerances within which the hypothetical "Mind of Theseus" is still the same mind? (I suspect this is a philosophical question and the answer is fully subjective and we have no way of knowing.)

Unfortunately that only helps for those with the necessary experience to discern good work, and also the time and desire to inspect it.

It's unfortunate that monetary incentives are notoriously vulnerable to being Goodharted into uselessness or worse. You try to offer a bounty on X [undesirable thing], people start [building/breeding] more of them and making a killing.
This is not to say incentives and/or subsidies can never work, only that implementing them effectively is a non-trivial task.

While they don't expect to literally see Jesus in person, there's a lot of emphasis on 'personal revelation' which is for the most part just conditioning to get believers to interpret their own regular ol' intuition/emotions as communication from the Holy Spirit. If someone believes that strongly enough, the brain provides whatever thoughts/feelings they subconsciously expect to 'receive'. It's both impressive and disturbing how well this cycle can work. Anticipation can easily function as a self-fulfilling prophecy as long as the anticipated experience is fully mental and emotional.

And because this 'evidence' has been accepted by them, they also expect their prayers to be able to miraculously heal sickness/disease (except for when it doesn't of course; "God's will" etc etc.)

I think they are genuinely unvaccinated. They believe (or profess to believe) in tons of quack medicine but AFAIK they don't spend loads of money on it. If they had a health emergency they'd still go to an ER, so they're not completely in denial of modern medicine.
