Emails take too long. Well, at least according to Google, which is why on Tuesday at Google I/O, the company announced a new Gmail feature called Smart Compose. The feature allows for artificial intelligence to auto-fill information in the emails you compose in an effort to cut down on the time spent typing up mindless messages. If typing emails is truly one of the baneâs of your day-to-day existence, this feature is here to alleviate that stress.
