The 'few seconds or minutes' wait is a mood spoiler and waiting for five seconds to 'skip the ad' is a total bummer. No matter what you do to avoid seeing ads on YouTube, the site developers always find a way to show you them to you.
The worst thing about these ads is that they are too loud and not related to the video you are about to see, because of this often the viewers lose interest in the video and choose not to see it, and down the line this might cause a lot to the video-maker or the particular brand/person that video is associated with; lesser views, less subscriber.
