It's extremely hard to communicate long distance underwater, especially to do so discreetly.
A coded sonic pulse could have exceptionally long range. Sure your enemies would detect it, about half a second before they detect the drones.
A more practical concern is simply temperature and how long the drone's power supply can survive in the cold ocean.
Because insurance would then just lowball the cost of everything.
Insurance needs to either do what they say they do, cover x% of procedure cost with a maximum yearly deductible or we need to be talking about why we have insurance in the first place.
We need new regulations around health and insurance. Ideally, public insurance.
They do. Many, many billable items are priced to the limit that insurance will pay. Insurance and providers have agreements on the prices they can charge for certain procedures or supplies.
It used to be the norm that insurance would pay their maximum and leave the rest to you. Sometimes the provider would waive the difference, sometimes it was billed to you.
The cost of healthcare is 100% an artefact of insurance price fixing and absolutely nothing else.
