What is a tensor processing units? What do they tell us about future?

The TPUs or tensor processing units are google’s own harware creation that supports the tensor flow software, which too has been created by Google. Google started using TPUs in 2015, and made available on their cloud platforms from 2018 onwards.

Does this hint towards the end of running codes on Jupyter notebook and start moving towards cloud based products that are much more powerful and can analyze lot more data in one go?
