I yet have to find an embedded product with an 18 year life cycle. But clearly, I could imagine there is some infrastructure stuff (power plant?) that could be affected.
For something that will use time eg to log predictable maintenance, you will be hit much earlier. Imagine a criticial piece of infrastructure marking essential repairs for 2038 or later due to a part needing replacing every 15 years. there could be thousands of such parts with different replace/repair times and they could be managed by Boeing. You wouldnt want that.
There were some financial systems hit in 2018 because they used to forecast up to 20 years ahead.

But yeah, that old stuff is used for decades sometimes sometimes. The Dutch IRS is still using quite a few computers from the late 80's and early 90's. They don't want to replace them, but they also have trouble finding someone trained to support those PC's, but at least they are still running (for now).

I would have assumed something like FreeRTOS would be the tool of choice for this applications.

Yes you do fine elevators with Linux and traffic lights controllers with Linux do exist. Do note 32 bit micro-controller running Linux the current builds here.
Of course not elevators and traffic lights use Linux but quite a few do.
Elevators the core is normally bare metal logic but the remote control system is Linux based. Just think about the fun if that elevators remote control computer goes stupid due to date issue so that elevator takes you to the top floor and refuses to go anywhere else.
Traffic lights system depend on the design some of them it is possible if the Linux OS screws up to result all green lights in all directions that is not very safe because some of those are fully linux embedded controlled..
Please note this is only the tip of a very big list of hardware. The usage concept of internet of things is a lot bigger than what most people think and can be a lot more dangerous.
Yes full blown network stack is absolutely common in these things. So running traffic lights with a remote webpage for configuration and alteration of the system is not unheard of same with elevator systems.

That just goes to show that the SLTS kernel and an SLTS distribution isn't a bad idea. And we thought Debian was old

Then there are items like elevators some of those are running 100year old + controllers so new ones of those can exceed the 18 year life cycle very simply.
