Because 20-year-old people with 200 IQ exist, and their brains consume approximately 3 MW-hr by age 20. Therefore there are no fundamental physical limitations preventing this.
I think this calculation is invalid. A human is created from a seed worth 700 MB of information, encoded in the form of DNA. This was created in millions of years of evolution, compressing/worth a large (but finite) amount of information (energy). A relevant fraction of hardware and software is encoded in this information. Additional learning is done during 20 years worth 3 MWh. The fractional value of this learning part is unknown.
Initialising a starting state of 700 MB at 10^-21 J per bit operation costs about 6 picojoules.
Obtaining that starting state through evolution probably cost many exajoules, but that’s irrelevant to the central thesis of the post: fundamental physical limits based on the cost of energy required for the existence of various levels of intelligence.
If you really intended this post to hypothesize that the only way for AI to achieve high intelligence would be to emulate all of evolution in Earth’s history, then maybe you can put that in another post and invite discussion on it. My comment was in relation to what you actually wrote.
