It mainly comes down to the software and algorithmic techniques.

I'm not convinced. The architecture of a computer, with its extremely fast CPU cores and its extreme bottleneck of a memory bus with a tiny cache set up in a hierarchy is radically different from the architecture of the human brain.

The brain is parallel on an unimaginably larger scale than anything we've ever built. The brain also doesn't put a wall between "storage" and "compute." I think there are tons of problems the brain solves easily with parallelism that would be bottlenecked by memory latency on a computer.
