Real, but naive, question: does TensorFlow have meaningful share outside Google? I've been in the HuggingFace ecosystem and it's overwhelmingly PyTorch, IIRC 93%, (I can't find the blog post that said it, but only gave it 2 minutes)
TF used to be the most popular framework by a large margin, so a lot of things that were started 5+ years ago are still on it. PyTorch is most popular in places that only started more recently or have the ability to switch easily, e.g. new startups, research, LLMs, education, and companies that have the resources to do a migration project.
A fun thing is that even in Google JAX is now preferred across researchers and slowly taking over the share.
Tbf JAX is super nice. Even easier than PyTorch in many ways and astonishingly fast. XLA is super powerful.
Best alternative for web imo (perf generally beats onnx for web)
