In fairness, the performance/size ratio for models like BERT still gives GPT-3/4 and even Llama a run for it's money. Their tech isn't as product-ized as OpenAI's, but Tensorflow and it's ilk have been an essential part of driving actual AI adoption. The people I know in the robotics and manufacturing industries are forever grateful for the out-front work Google did to get the ball rolling.
You seem to be saying the same thing- Googles best work is in the past, their current offerings are underwhelming, even if foundational to the progress of others.
