I've already started. Most of my YT viewing was from the smart TV app, and since I can't block ads from there I simply don't use it anymore. It's still OK on PC, and on mobile I use Grayjay. On my TV, I just watch shows and anime nowadays instead.
If you have an Android-based smart TV (or a device that runs Android connected to your TV), you can use SmartTube. It blocks ads, supports SponsorBlock, and casting from your phone, among other things.
