From the hubby from the discussion of the smart tea machine:
It will also be useful to have a wife, or at least a permanent girlfriend. They (women), according to rumors, have multi-tasking and a built-in memory block of various capacities. Some come with a different set of pre-installed cooking programs (brush, delicious potatoes...). The main thing is to be afraid of counterfeits in bright packaging. Often they have an increased consumption and do not produce any useful work, while releasing a huge amount of useless energy in the form of foreign noises and sounds.
