Ceramic capacitors should be fine, right?

The pico microcontroller, on the other hand, has normal flash and won't last very long. Here's an interesting article:

Maybe keep it in the freezer?

Otherwise I would expect tin whiskers or some other process to dominate reliability at long periods.

Can't find info on what kind of capacitors they use but [1] suggests certain kinds of ceramics can only last ~10 years.

More generally, all electronic components can fail [2] and there's a lot of such components in this device. This is applying component-level thinking to a systems level problem with no real way to verify their claim (they don't even claim to have done any aging test to try to simulate how long the device could last) and why this should be called out as nothing more than a marketing gimmick.
