Now that it's pretty close to actually being here, the grim reality is that anyone who was expecting the status quo to just march on like always is going to get screwed over; and the a new wave of successful businesses will adapt to it and thrive.
It's called 'disruption', and it's a bit disappointing to see people here of all places complaining about it.
Sure, I get it, it's google, and if it was some nippy unicorn doing it people would be more enthusiastic, but ML is hard to do right, and having someone who's actually pushing the boundaries of whats possible is, in my opinion, pretty cool.
BERT made a huge contribution, and if this eventually flows out to everyone else to use, that's great news.
...and, if google stops sending traffic to some websites, well, too bad. We'll adapt; so will others.
The ones that can't will disappear.
