For some things modern technology has been a Godsend. But for others, such as sewing machines, fans, toasters, coffee pots, and things that used to be made from metal, Bakelite, wood, and mechanical parts modern technology has made them far worse. They are no longer durable.
The current computerized plastic and pot metal sewing machines might do wondrous things when new, but they just will not last.
In that light they are a waste of money.
