You're right and missing main point at the same time. The reasons why biology didn't evolve what we discovered don't matter. What matters is that it didn't, yet they can exist and outperform. Similarly brain is not an upper ceiling for intelligence. We can create more intelligent machines than us. Things like energy efficiency don't matter as much - when we run large models, nobody cares that it may require more energy than two sandwiches and a beer per day. We do care about energy efficiency but not at scales of biology.
