Gary wants to know about Google Voice with the Pixel phone. Leo says that Google Voice started as GrandCentral, which he used to use for his office. Then Google bought it and created a central phone hub for everyone. It gives you a new universal number and then rings different phones until it finds you. It also has custom voicemail boxes for people in your contact list, strangers, close friends, and unknown. It also sends you a text message with the voicemail. And it's free to use.
Gary also wants to know if there's a security issue through USB. Leo says yes. People who are sophisticated about USB don't connect to a stranger's USB charger, as malware can live in it. Charging-only USB plugs could be OK, though.
