They really are. On desktop they're unskippable (unless you reload - often 10+ times to get something short enough or no ad), they're never relevant or interesting, they're ridiculously long (often over a minute, I've seen them significantly longer than the video). They're noise, and the signal/noise ratio is worse than I've ever seen on TV. If a video's longer than about 10 minutes sometimes it cuts in the middle of a sentence to show another irrelevant, long, rubbish ad too.
Truthfully, with all of the great minds that are at google, it's a bit shocking they haven't found a way to make the advertisements at least a bit more amicable to their viewing audience. In my mind, there's no reason that some sort of content analysis couldn't be done during the upload to check the overlay boundaries and see if "crucial content" like text is present, and set flags in the meta-data so that the ad software can avoid those time stamps. Or on the sound issue, do some advertisement audio balancing based on the volume of the previous and following video so you don't suddenly get audio blasting through speakers/headphones.
To me these seem like relatively simple user experience tweaks that really would make it easier to digest advertising through the service.
Consequently, using Safari on mac and click-to-plugin, you can force an HTML5 player, which seems to not allow the pre-play ads or the overlay ads at all. I've found the experience much more enjoyable via this method.
Honestly, the ads are easily the worst part of youtube for me. I'm logged into my google account, everywhere, all the time. And yet they still appear to go out of their way to find the least relevant ads they can find. Adsense doesn't seem to suffer the same, so this disconnect has always puzzled me.
So... are you a human? Then this ad might be of interest to you :P
Why? The ads aren't that bad.

From a business perspective, autoplay is good as it leads to more videos being watched.
