Bill Gates has announced that he plans to create a new unit, hiring 3,000 people to take to social media, put out messaging, and “help propagate accurate vaccine information in the future,” CNBC reported. 
Billionaire Bill Gates wants social media to be a place with “good messages” from “people of trust in the community, such as political and ethnic leaders.”
Gates made the statements when being asked about Elon Musk’s acquisition of Twitter and the future of free speech on the platform.​“I kind of doubt that will happen this time, but we should have an open mind and never underestimate Elon,” he said.

One of the reasons Gates feels Musk could make Twitter worse is the SpaceX CEO’s stand on free speech.
“How does he feel about something [on Twitter] that says ‘vaccines kill people’ or that ‘Bill Gates is tracking people?’” Gates asked.
“What are his goals for what it ends up being? Does that match this idea of less extreme falsehoods spreading so quickly [and] weird conspiracy theories? Does he share that goal or not?” Gates said.
Bill Gates feels social media platforms have a role to play to prevent misinformation from spreading.
