Nicholas Thompson, editor-in-chief of WIRED, helps us make sense of today's stories in technology:
What is going on with Elon Musk's startup, Neuralink?
He demonstrated on a Friday night, this small little sensor you put into your skull, or as he showed on TV, into the skull of a pig, it can read and write electrical signals into the brain. What will it likely be able to do? It may, for example, be able to process simple thoughts, allow people who have lost ability to move their arm, to move their arms again. The long-term promise, which Musk talked about, would allow you to download and rewind your memories, highly unlikely and highly speculative.
Why does Walmart want to buy TikTok?
Well, TikTok will generate tons of revenue. It's a booming platform and there are lots of possible ways it could integrate with Walmart. E-commerce, advertising, branding. I don't know if that's a great idea for TikTok but it does make sense for Walmart.
