Unfortunately, customer support is a hard problem. Despite all of the advances in NLP, I still abhor automated customer support systems when I have a complex issue. Just let me talk to a human.
Google long ago ran the numbers on providing human customer support and realized it's not the sort of ultra-scalable business function that they like to invest in. Rather, they'd like to believe that they can build software systems that don't require human customer support. As an end user, this feels like too much hubris and not enough empathy. It may work from the perspective of a product manager looking at percentages on a dashboard, but it sucks as someone in the real world trying to get something done with one of their products that's not functioning as it should.
I use the full suite of Google Products, including Project/Google Fi. This article describes one of my nightmares— getting locked out of my Google account. I'm fortunate that I have good friends that work at Google that could help out in such a worst-case scenario. This blogger is fortunate, too. Undoubtedly, some Googler will read this post and help them out.
But the average person isn't so lucky. If you're Jane or Joe Schmoe in Middle America, you're going to be screwed when your Google account goes haywire. I've had friends whose Google accounts have gotten into weird states that prevented them from using Google services for no obvious reason. I suspect this is due to an unfortunate consequence of Conway's Law [1] at work in Google's identity implementation.
