Neuralink's brain chip to begin human trials in 6 months

HN headline and linked article's are quite different, HN headline here is clickbait. "Elon Musk expects Neuralink's brain chip to begin human trials in 6 months" and that in no way really indicates that it will.

I thought Elon wanted Humankind to become even more entities. So why he tries to kill them instead?
