One of the most important ones is not on the list: narcosis (1846).

air conditioning.   with no AC no clean room, no clean room, no semiconductors no microchips. so no electronic, one can imagine what electronic means in today's world, pretty much everything.

oh and the whole concept of refrigerant compressing and evaporating paved way for refrigeration,  where would we be today if we did not have that?

i'd say it is one of the most important inventions , basically imo mister Willis Carrier made today's world possible
