You know, it really makes me step back in amazement sometimes when I look at what progress has been made in the last forty-ish years.

Mostly I see it that way too. But I sometimes have to deal with the negative aspects.
The input for the CFLs is just one example of equipment that takes non-sinusoidal current from the supply. Computers, televisions, anything using SMPS does similar things.
The result is that they pollute the electrical supply.
You then need to add equipment to mitigate the effects.
Progress is rarely without some pain.
