But I have an opinion on Google translate. From my experience, it is not clearly leading in comparison to other tools by smaller companies.
If Google is leading in AI, why don't they have any clearly leading consumer products in this area?
For machine translation, they used to be clearly leading, then deepl arrived and I think they are roughly on par (or maybe deepl is better, but also has fewer languages). Do you have other companies in mind?
As mentioned above, in research they have some great results, translating those to products is not always straightforward of course - or even possible.
It is true, however, that TensorFlow is now considered outdated, with pretty much all the community switching to PyTorch (originally developed by Facebook, now handed over to the Linux foundation). But indeed these are not really products (i.e. they don't bring in the money they cost, by far), more like open source projects.
