Google brings out BERT. So What?

[Geek-9pm]

It is hardly news. Or is it? 

Google claims it is the biggest thing since sliced bread. I don;t think so.
In fact, I have no idea why they are raving about it.

Can anybody here explain to me why BERT might be important?
Here is a new article about it.

I don't give a hoot.
