Firstly, our evolutionary ancestors were tropical animals with no history of hibernating: humans have only migrated into temperate and sub-arctic latitudes in the last hundred thousand years or so.

The disadvantage is that it will continue to consume power because of RAM’s volatile nature. … On the other hand, hibernating computers need more time to resume because they have to fetch the data from the hard drives (instead of RAM) and then write these values into RAM, making the whole process more time-consuming.
