On a social media platform, Musk disclosed that Nolan Arbaugh, the inaugural human subject in the trials of his brain - computer interface firm Neuralink, is set to have a second chip implanted with the goal of regaining mobility in his legs. Explanation: - “revealed on a social platform” is adjusted to “disclosed on a social media platform”. “Disclose” is a more formal and commonly - used word in such contexts, and “social media platform” is a more widely - recognized term compared to “social platform”. - “the first human participant” is changed to “the inaugural human subject”. “Inaugural” adds a sense of formality and significance, and “subject” is a more technical term often used in medical and scientific research contexts. - “plans to undergo” is replaced with “is set to have”. “Is set to” is a more natural and commonly - used English expression to convey a future intention or arrangement. - “aimed at restoring his leg mobility” is rephrased as “with the goal of regaining mobility in his legs”. This version is more detailed and clearer in expressing the purpose of the implantation.
