Because bicycles use 5x less energy per mile than electric scooters, which would be a reasonable analogue for slow electric delivery robots [0].

By comparison, fossil fuel conversions are about 30-45%, depending on the energy source [1].

That's a really, really weird baseline to use. Turning off a robot when not performing a task is standard procedure. Turning off a human when not performing a task is not standard procedure, and is frowned upon in polite society.

This is your mind on HN.
Well for one thing, the robot doesn't need to exist at all. Humans are going to be eating and breathing regardless of demand for burrito delivery.
$500 per adult per month (~$1.4T) - existing welfare.
for $1000 per month it would cost $3.1T.
What about the children? $1,200 for every adult + $400 for every child 4.1 trillion/year
The federal budget is 6 trillion/year.
There would need to be deflation for 1,200 a month to have the buying power of the average income now. Right now that's minimum wage.
Oceans filled with plastic would be "good" for something. Just probably not us. Maybe robots?
