Your position is dangerously close to solipsism. You allude to Occam's razor but it also answers your question. If the simplest algorithm does not imply limiting the amount of 'stuff' (universes), why would it limit the amount of observers?
And when I face an undecidable with equally plausible answers, I'm forced to test each view to see the results: what's life like with view x vs. view y. That result becomes the metric for a view's worth.
And honestly that could be solipsism. Although I know it as a similar concept some call "subjective reality". Again I don't believe in solipsism or SR, I'm just pointing out that either could be true and you could never know. I do believe in the multiverse though.
I always thought computers as conscious would prove consciousness was physical. I didn't realize my mistake till recently.
