I got sick of seeing 40 minute long videos on the dumbest things. Even if it is a topic I'm interested in the pacing of such a video makes it so not even 5 minutes of it are worth watching. All good youtube videos are under 20 minutes. Some of the code is mislabeled because I decided having the script tell youtube I'm not interested is a stretch goal and for the sake of the end user, simply hiding those videos is good enough.

(function() {
    'use strict';

    function convertDurationToSeconds(text) {
     return text.split(':')
                .reverse()
                .map((i, idx) => parseFloat(i) * Math.pow(60, idx))
                .reduce((a, b) => a + b, 0);
    }

    function findAndHideLongVideos() {

        var selectors = [
         'ytd-compact-video-renderer.style-scope.ytd-item-section-renderer',
         'div#content.style-scope.ytd-rich-item-renderer'
        ];
        for(let selector of selectors) {
         console.log("hello from long youtube")
         const suggestions = document.querySelectorAll(selector);
         console.log({selector,suggestions});
         for (let suggestion of suggestions) {
          let durationElement = suggestion.querySelector('div#time-status span#text');
          if (durationElement) {
           let durationSeconds = convertDurationToSeconds(durationElement.textContent.trim());
            if (durationSeconds > 1200) { // 20 minutes
             //Hide it
             suggestion.style.display='none';
             //[Todo] Tell youtube not interested
             //Find and click the menu button
             //let menuButton = suggestion.querySelector(/* selector for the menu button */);
             //if (menuButton) menuButton.click();

             //Wait for the menu to open and then click 'Not Interested'
             //setTimeout(() => {
             // let notInterestedButton = document.querySelector(/* selector for 'Not Interested' */);
             // if (notInterestedButton) notInterestedButton.click();
             //}, 500); // Adjust timeout as needed
            }
          }
        }
      }
    }

    // Run the function periodically
    setInterval(findAndHideLongVideos, 1000); // Adjust interval as needed

})();

Also I made some artwork because that is absurdly easy now:
