There's nothing worse than crappy autoplay videos on websites and I'm constantly having to mute them so I can read content and not listen to them. However, from this point forward Chrome is going to do something about this
and it will learn your browsing behavior and start muting this stuff for you. According to Google, it will mute autoplay stuff for about 1,000 sites within six seconds. Also, they claim that once your browser is fully trained it should block about half of the autoplays you run across. This isn't perfect, but I'm sure over time they will increase the percentage of mutes. With that said, I'm glad I'm a Chrome user and this feature makes me like it even more.
