The problem with that line of reasoning is you're assuming the brain is a computer, or that it merely computes.
But that's just an assumption and there are many reasons a person, let alone a brain, is not a machine or a computer or an algorithm. That it is like it? Sure, in some insignificant ways, we have the ability to compute things. But is it an algorithm? No.
The idea that consciousness is an algorithm or a computer or a machine is an assumption that is extremely popular among people in the tech industry because it confirms their assumptions, and it makes them feel like they have extremely transferable knowledge. "I know about computers. Let's assume the brain is a computer and consciousness is an algorithm. I can now comment on the brain and consciousness."

But there is very little reason to accept that assumption. This review of Harai's Homo Deus does a great job of pointing out the dead-ends that assumption leads you to. [review](https://inference-review.com/article/godzooks#When:00:35:00Z)
