Generally, people who want their pool cleaned do so when they are conscious and have their pool very close to their home address. People who need ambulances are usually in a very different condition. That makes it a different prospect trying to chase payment.
And yet "slapping the keyboard faster" is all that AI does. It doesn't design architecture. It doesn't think. It doesn't reason. All it does is search for and copy-paste code from elsewhere on the internet. If you're lucky it might even be code that works and does what you want it to.
One thing that's often overlooked is the cost of administering a billing system. If you're going to distinguish between the insured and uninsured you need a system that keeps track of who has insurance. You need paperwork (or digital equivalent). You need accounts payable staff to send invoices and chase up unpaid bills. It can, counter-intuitively, work out cheaper just not to charge anyone.
AIUI one of the many quirks of the US health insurance system is that a lot of people have only minimal cover which doesn't include things like physiotherapy and rehabilitation treatment. That means that they often can't treat a painful condition at source so their only option is to mask the pain with painkillers.
Interesting bias to blame the woman. How do you know that the second twin wasn't taking advantage of their identical looks to convince the woman it was the same man she had slept with the first time? She may not even have been aware that he had an identical sibling.
The buried lede in that link is that mothers who don't have custody of their children are more likely to remain in close emotional contact with their children than fathers are when in the same position. So children living with dad still benefit from having both parents involved in their upbringing. Which undermines OP's assertion that this child would be better off without their mother around.
