Aren't Siri, Alexa, Cortana, Google Assistant etc all providing answers generated by NLP algorithms? People seem to be using them pretty frequently.

Google already provides no-click search answers by scraping data from a website and bolding a paragraph that may answer your question. The branding of the original site is removed on these snippets.

How long before Google decides not to link out the website altogether?

I don't use those products, they only work for very specific types of queries. While I expect they will make it more broadly useful, I don't see it replacing content sites altogether.
