Why is no one admitting that even though resources like RAM, CPU, etc. are plentiful nowadays, they should still be conserved?

Computers have gotten orders of magnitude faster since 2016, but using mainstream apps certainly don't feel any faster. Electron and similar frameworks do offer appealing engineering tradeoffs, but they are a main culprit of this problem.

Sure, the magnitude of RAM/compute "waste" may have grown from kB to MB, but inefficiency is still inefficiency - no matter how powerful the machine it's running on is.
