Self-Driving Cars
Self-driving cars were introduced in the early decade with a lot of pushback from potential consumers. After tedious testing, some self-driving cars were released to the public. The Tesla models are probably the most popular on the market as self-driving cars, and they're pretty successful. Even Uber and Lyft are releasing driver-less rideshares!
Google Assistant
The Google Assistant can be found on all Google devices but is most commonly used on a Google Home service. Just by using voice commands, you can order groceries, make a list, or even post to Twitter. Everyone's always wanted a personal assistant, right?
