Agreed. If you have a CPU from 2012 onwards, 16GB of RAM and an SSD, that’s a respectable hardware setup. It might not be the fastest piece of kit on the planet, but I don’t see any reason why it couldn’t last another 3 to 5 years without feeling slow.
Electron apps invariably make such kit feel slower than it actually is. You can get good performance out of even older hardware if you treat it well and load it with good software that respects the hardware.
