Deadlines? Imagine you have an important exam/audition in two days, but haven't had the time to study/rehearse properly. Then, tomorrow you look yourself in the chamber with your books/instrument and leave it when you're totally awesome. OTOH, since (IIRC) you are only allowed into the chamber twice in your life (and even if this weren't the case, you don't want to be 35 subjective years old 25 calendar years after the date on our birth certificate), you only do that for things you *really* care about.

Deadlines like that are zero-sum games, and so the impact is limited - it shifts around who wins the exams/auditions at a substantial cost (whatever it takes to use the HTC over just living in the real world). On the macro scale, I'm not sure how much it matters at the margin: if someone needs a HTC just to study for an exam...

So is poker, but it doesn't mean there's no point in playing it. (Also, they are only zero-sum if the number of candidates who will pass is fixed in advance.)

Well, I think a lot of people play poker who shouldn't...

As for not being zero-sum - that may be true, and I assume your argument is that the additional return justifies the use of the HTC. But if you're not using the speedup aspect but the pocket-universe/precommitment aspect, why not just run cheaper facilities in realtime which approximate prisons for students? They need a week's practice, they enter the prison a week before the audition...

This has the tremendous advantage that we could do it already, right now, in the real world. Yet I've never heard of such a thing.

I think you may have misunderstood my idea. I was thinking that candidates would choose to go into the HTC, not that they would be required to. (And when I said “things you really care about” by “you” I meant candidates, not examiners.) And I wasn't assuming it would only work if you cannot leave the room before the 24 clock hours/12 subjective months -- indeed, it would work better if you could decide to stay as little or as long as you want.

I suspect that anything I am sufficiently non-motivated to study/rehearse that I haven't used the available time to do so, I will probably end up not using the time in the chamber to study/rehearse terribly efficiently, either.

But if you have a year to do it, you don't have to do it efficiently.

If you are going to blow an entire year of your all-too-limited life in the HTC, you might a well not go in at all and enjoy a higher quality of life while doing said inefficient studying.
