I don't think it's half as bad as that. Google Flights, Translate, the G-Suite, Firebase and TensorFlow have all been good products/software, though perhaps not world-changing.
I am a huge fan of TensorFlow.js, the examples, docs, etc. are really good. But, I am nervous about jumping in too deep in case it disappears. Regular TensorFlow is here to stay for the long term.
Saying that it works just like Altavista's Bablefish of yore is ridiculous, at least for the European languages I am familiar with. Translation quality as offered by all major services is leagues ahead compared to the state of, say, three years ago.
(Disclaimer: I work on a competitor to Google Translate)
