Of course we don't even know whether this sense of self is really purely attached to the brain. That brain is still connected to the rest of your body, and who knows what the body chemistry of the body donor will do to the new brain? Maybe we'll end up with a completely new person. Maybe not all memories will survive the transplant, but even if they do, you'll have a person who has the memories of the brain donor, but will be recognised by everybody as the body donor.
Mind you, if you transplant the entire head and not just the brain, this issue will lean a lot more strongly towards the head donor.
Imagine just one aspect of this. A thyroid disorder.
If the donor body was hyperthyroid, the head transplant would result in someone with the symptoms of hyperthyroidism. Angry, irritable, racing pulse, etc. If they had hypothyroidism, they would be depressed, lethargic, etc.
And that's just one organ in the body. It could radically alter the "person" who they are presuming lives only in the head.
There was some bad UI with the web. It would pop up a window to warn you to only send money to people you know, but it was a window you couldn't move to see who you were sending money to, in case you clicked the wrong person!
But that's better than the experience I had with the app when I paid at a McDonald's recently. I was expecting a screen which said something like "You are about to pay $9.72 to McDonald's Corporation. CONTINUE/Cancel.
Instead, when I put my thumb on my phone's fingerprint sensor, here's the feedback I got: (vibrate)
No information on who I was about to pay or how much I was about to pay. And afterward, absolutely no information about who I just paid or how much I paid them.
I went into the payment history screen and they payment wasn't there either, although it showed up about a minute later.
How is that acceptable?
I would NEVER use the app unless I lost my wallet!
Using the Google Pay app at a point of sale was a terrifying experience.
The article explains why.
> Just like with Google Allo, SMS-based authentication means there's no desktop support at all. The Google Pay website is being stripped of all its useful functionality because a browser does not have a carrier SIM card and therefore can't be authenticated by the SMS-reliant system.
