Famously, the Linux kernel does not have a stable ABI for drivers. As a result, by far the majority of drivers are in-tree, maintained by the kernel folks as part of the kernel.
The Linux approach has the downside of not having the drivers if a vendor has not been working with the kernel community before launch (or for those who haven't upgraded to a kernel that has the driver, e.g. a LTS release).
On the other hand, the driver is maintained by kernel developers, not created by the hardware developer who is not getting paid after they sell the device. This helps avoid abandoned / vulnerable drivers, or having the hardware dev search for... alternative revenue streams, as in this case.
Holding it on your hand is insufficient. Using it may require an external server or certain chosen proprietary software that could be taken from you at any time or itself requiring an external server.
The bits you want to own must be entirely self-contained, and able to be screwed using whatever software you may choose, especially open source (though if the format is fully documented so that anyone can create and distribute a viewer, the software need not be open source.)
No, there is a steady stream of teachers being fed into the maw of public education. The pay is low and job security is terrible until you get tenure. My wife was a teacher; I have heard horror stories.
You get paid based on a combination of how much money you earn your employer and how easy you are to replace. Schools get paid by taxes, and there are a ton of them produced every year. So, the pay is abysmal.
"The United States spent $15,500 per FTE student at the elementary/secondary level, which was 38 percent higher than the average of OECD countries3 reporting data ($11,300). The United States had the fifth highest expenditures per FTE student at the elementary/secondary level in 2019 after Luxembourg, Norway ($18,000), and Austria and the Republic of Korea ($15,900 each)."
> It's literally less traumatic for a child to be in an active war zone than to be separated from their parents.
Unless they happen to go to war themselves, vanquishing an evil queen with the help of a lion and becoming kings and queens, and reigning for a long while themselves.
Those kids seem to mostly turn out alright. Small sample size though.
