I suspect this wasn't your intention, but I feel this heavily undersells how much work is involved in "scaling up" to simulating a human brain. I wouldn't even say that it is inevitable, because there are so many unsolved questions and unknown-unknowns.
There are decades of research and we are still an unknown and large number of years away from doing this. Fusion power is more tractable that this.
It's not even clear whether our current approach to computation will ever be able to do this. We might need completely novel types of computers, maybe organic-machine hybrids.
I'm not even touching on the very real and serious ethical questions of simulating human level consciousnesses.
Also note how my "just" only applies to scaling from mapping a grain-of-rice-sized piece of human brain to mapping a full human brain. Going from there to simulating it would be another big leap, never mind the challenges to simulate it in a way that actually produces results comparable to the actual brain of that person.

Hence the scare quotes around just.
