Genius ^Well for one, you are about 2 months late lol. Second, It's a layout change. Not the end of YouTube. Third, How does everything look the same? If someone has the same banner as you, sure. But if they don't, their channel is different than yours, therefor their channel does not look like yours. It's actually a really good layout.
Accept change, and make the best of it. Complaining is going to get you nowhere.
