> but this is happening right now to a friend of mine's gmail account
I can't stress this enough but please enable OTP on your accounts. Facebook, gmail, and even your Windows system if you are paranoid enough. Yeah it adds some hassle - but the value of increased security far outweighs the hassle. Also backup the OTP codes somewhere.
> Scammer was able to social engineer the cell phone company to forward his number
If they are in the US please tell us the name of the provider so we know not to ever use them. This isn't the first this kind of attack has happened [1] (shame on you DigitalOcean). I use Gandi and they state in their documentation that they will not reset it if you ask them [2].
> Its so disturbing that there is absolute nothing you can do to reach Google once this happens.
It's a free service - what do you expect? I've heard this story many many times. Yes - google makes billions in profits and could in theory hire someone to handle gmail issues. But, they don't and it makes sense from a business point of view (why spend money on a guy who will support a service that doesn't make money?).
> It could happen on anyone's cell phone as well, how many fortune 500 companies have higher up employees with cell phones and gmail accounts?
If a Fortune 500 company uses gmail they would buy the google apps for work. If they buy google apps for work they get an 800 number to call if they have problems (and most likely a dedicated account rep because they are probably buying 1000s of accounts).
> Imagine in the future trusting google with a self driving car and home automation
Again - you would be giving money to google. And in return you will get support. I'm not saying Google is perfect but if self driving cars become a thing I'm sure (hope) there will be an 800 number you can call when your car becomes sentient.
