Elon Musk says humans must become cyborgs to stay relevant. Is he right?

Elon Musk warns humans must merge with AI through brain-computer interfaces to avoid becoming obsolete. Current BCIs restore motor control or enable communication for paralyzed patients, but are limited to decoding simple commands. Researchers like Bryan Johnson seek higher bandwidth interfaces. Some experts, including Miguel Nicolelis, argue the brain is not computable and humans won't become irrelevant. BCIs could enhance trust in AI, but raise privacy concerns about hacking. Most agree we are far from realizing Musk's vision.
