When we threw it out and started using useState() hooks our life got so much better!” (or maybe just “once we started using hooks our life got so much better”).

And yep, I am still using redux, even though react hooks, which supposedly made redux obsolete and old-fashioned, arrived back in 2018 (which is also the same year I started doing frontend programming).
