Google has the compute, from the comparisons I have seen Bard smokes GPT-3.5-Turbo on response times. So my guess is that internal politics prevents them from putting out something better. There would have to be immense pressure from the search division to not make them obsolete.

Bard is also a fair bit worse than GPT-3.5, though, so that can be a function of model size.
