The Third-Generation MacBook Pro Butterfly Keyboard

The surprise announcement of a new MacBook Pro keyboard led to people wondering if the third-generation Butterfly keyboard would alleviate any of the issues presented with the second-generation. Apple advertises it to be quieter, which seems to be true. However, iFixit says that this is actually a side effect of Apple's new measure to keep dust out. There is a silicone barrier beneath the keys to prevent dust from getting into the keys and creating input issues. While it's not a hundred percent certain that this barrier was made to prevent dust from entering the key, it certainly is a pleasant surprise at least.
