Partly agree, but it's not like you don't have to use resistors anywhere else with Arduino and the likes. Just to light up a LED you will need some and usually

Partly agree, but it's not like you don't have to use resistors anywhere else with Arduino and the likes. Just to light up a LED you will need some and usually there are plenty included in starter kits. At least where I live there still are a couple of electronics retail shops where you can buy spare components. Also arguing that desoldering smd resistors is easier than finding a through hole one and plugging it into a breadboard or soldering into a prototype board is a bit of a stretch.
