Is it my dehumidifier?

Nah, you can just sudo umount /path/to/device and then remove it. No need to power off the pi.

Out of curiosity what did you install ? And what did you install it on ?

I don’t buy it. Large scale ecological collapse and the following mega migrations, is going to butt fuck the fuck out of industrialised countries way before a wealthy Nigerian can luxury shop for migration destinations.

Also most industrialised countries would mostly need skilled labour and not random untrained immigrants, which of course would be the majority by far of future migrations.
