Here's a 100W-equivalent bulb: https://www.ikea.com/ie/en/p/solhetta-led-bulb-e27-1521-lume...
It costs 6 euro. I'm _fairly_ sure that incandescent 100Ws didn't cost six cents. I bought a few of these (actually a cheaper non-dimmable model which is no longer on Ikea's confusing website, from a cursory search) in 2016, when I moved. They're still working fine.
Whereas incandescents failed _all the time_.
