There was never a time people were forced to get vaccinated for something they already had.
Rabies. The treatment protocol is wound care, a dose of HRIG if you've never been vaccinated and a four dose vaccine series. Because it moves through the body so slowly, vaccine administered after exposure is an effective treatment, allowing the immune system to rally more effectively with the HRIG jump-starting the process. This is also the reason the HRIG dose is not administered in the same body part as the first vaccine dose - the vaccine trains the body to produce HRIG so it's more effective to inject the initial bolus of antibodies somewhere other than where the vaccine is injected.
If AI is a bubble and it pops...
AI is a bubble and it will pop. It's like any bubble centered around some new tech that's obviously transformative but no one is exactly sure what it will be practical to use for and people are willing to invest startling sums to throw it at the wall and see what sticks (see the Internet back when). It'll pop, pieces will be picked up and in a decade from then we'll all be using AI in whatever forms ended up being useful on a routine basis and not thinking too hard about the rest. Presuming tensors end up being the right construct and aren't replaced by something else entirely, there's a non-zero chance that every device that AI is considered useful for will have a TPU and storage for a local model included rather than requiring being internet connected to access AI.
I suspect it's going to see lots of use in the medical/biotech fields in particular - specifically I could see an ML system rapidly outpacing human ability at diagnosing disease from medical imaging given several ten thousands of images and diagnoses to train from. Wouldn't trust it wholly (especially not at first), but as a pre-processor setting priority levels for specific imaging results (as in these look normal mark them low priority, that one sets of cancer alarm bells mark it urgent), even going so far as to tag with what it thinks is wrong and where to be checked by an actual doctor who can do actual further tests if warranted I could see it improving patient outcomes. We've already got one that can predict protein folding.

Hey now, we have some of the best healthcare in the world if you can afford it, and healthcare stats that make it absolutely clear how few can.
