Archaic and Dated
Well, I'd ask by what comparison. 90% of today's washers are copying a 1960/70s design and the concept of a central agitator is about 100 years old. Consider that today the most practical items sustaining all of humanity like wheels, transformers, motors, ect are either 125 year old or centuries old. If you don't believe me have a look at Nikola Tesla's patents many of which are found through out the typical family home absolutely unchanged from when they were drawn up 2 centuries ago.
There comes a point a creation, invention or idea becomes a timeless classic. I will agree that GE should have reduced the space between the inner and outer tubs but other than that GE FFs were overall nice washers that proved themselves to folks who were in need of their unique qualities.
Talking about smells the post FF washers with their meshed wash basket and neutral drain would become hands down the most disgusting washer ever made IMO. Don't get me started, lol.
