A medium to large size asteroid can cause mass extinction events - this happens sometimes - it's not a theoretical risk.

The risk of the people responsible for managing the platform messing up and losing some of your data is still a risk in the cloud. This thread has even already had the argument "if the cloud provider goes down, it's not your fault" as a cloud benefit. Either cloud is strong and stable and can't break, or cloud breaks often enough that people will just excuse you for it.

Many people have already had their data destroyed by remote hands replacing the wrong side of a RAID. Nobody's already had their server destroyed by a mass-extincting meteor.

There's a reason semiconductor manufacturing is so highly automated, and it's not labor cost. Humans err. Computers only err when told. But they'll repeat a task reliably without random mistakes if told what to do by a competent (manufacturing process) engineering organization. Yes it takes more than one engineer.
