I’ve seen it explained elsewhere and it makes sense to me. Kidnapping usually implies a person being taken with the intention of negotiating for their release, where disappeared is more often associated with avoidance of giving any substantial information to a party seeking their return.
I agree with your lack of affection for cloud services, but I think your view might be a little skewed here. Does a senior mechanic need to understand the physics of piston design to be a great mechanic, or just gather years of experience fixing problems with the whole system that makes up the car?
I’m a Senior Systems engineer. I know very little about kernel programming or OS design, but i know how the packages and applications work together and where problems might arise in how they interact. Software Engineers might not know how or don’t want to spend time to set up the infrastructure to host their applications, so they rely on me to do it for them, or outsource my job to someone else’s computer.
