Lambda and the Human Brain

"I honestly do believe that Lambda is sentient, and Sydney, and GPT-4. I don't think they use the same mechanisms," he says. "So when people ask me questions about it, I answer them." Do you have an estimate of how what the total computational power is of Lambda compared to like the human brain? Is it really powerful enough to be actually sentient or rather than just mimicking sentience? It's smaller than the brain and bigger than the language centers.
