The term 'boot' comes from 'pulling oneself up by one's bootstraps'. There was a time when the computer operator had to input a program step by step using front panel switches so as to 'teach' it to load a paper tape. That paper tape 'taught' it how to load the bigger tapes but checking for errors etc. When the computer was switched off all of that 'knowledge' was lost, (no hard drive!), and so the process had to be repeated next time. Later computers had these first rudementary steps 'built in', the 'BIOS' of today's PCs. For some strange reason, despite all the incredible size of today's hard drives, most PCs still go through a process of 'booting up', building up all the processes needed to run 'Windows' etc. I say strange, because it ought to be standard just to save the machine state to disc on shut-down and pick it up again on start-up. Old habits die hard I expect!.. so when you boot (where did that word come from) up, you get welcome owner, but never 'how are we today?, did you sleep well? or more importantly can I make you a coffee? Isaac Azimov you were wrong.

Aren't all these 'Alexa'-type devices going the way you want? Personally I think they are encouraging bad habbits in our children - "Alexa! Do this for me now!" (Alexa thinks: "What happened to the 'magic word'?").
