Ambient light sensors are categorized as low-risk by device makers and can often be accessed directly by software (or malware) without any permissions or privileges. Nevertheless, previous studies have shown such a rudimentary sensor can provide enough information to infer keystrokes on a virtual keyboard and steal a device PIN, about 80% of the time. The new research shows what an ambient light sensor can do when combined with an active light source component – namely the device' screen.

Fascinating stuff. Almost like we shouldn't use computers at all!

Air-gapped computers that remain unconnected from the internet (and all other networks) are still very low risk. They mostly only remain vulnerable to physical possession attacks (although yes, it's still possible to record what you're typing by various external spying devices).

At this point you basically have to assume that if you are using something electronic it is spying on you ☹️

I'd say its nothing to worry about for now. I guess it wouldn't hurt facing the screen away while you write down a seed.
