Rarely do I need to answer a simplistic question in line with "what's the time now".

Its rather some deeper info that first few lines of wikipedia article covers, sometimes more. Is your use case valid? For sure for you. But it wouldn't be enough for me, not for the price, upfront and hidden, not for the creepiness it potentially brings. The real time and energy saved for me would be tiny - but that's me. I can still do a bit of 'work' myself.

This reminds me of my recent trip to Aconcagua, highest peak in South (both) America. One US lady had this electric air mattress inflater, and she ran off the charge. She was bragging how smart is she for having such appliances. Rest of the group just smiled and inflated our mattress ourselves, even in 6000m high camp. If you can't do 10 full lungs blows yourself and spend that 1 minute preparing mattress, you shouldn't be up there, by huge margin.
