I've been wondering about the black eye stuff myself.

Bryan Johnson (entrepreneur)
Kernel
Johnson started Kernel in 2016, making a personal investment of $100 million.[31] The company's goal is to build an implantable device to improve brain function in humans, such as memory, while interfacing with artificial intelligence (AI). Initially, the company is focusing on applications for patients with neurodegeneration such as memory loss.[32]
Patients with epilepsy are among the first to test the technology, which relies on algorithms that mimic the brain's natural electrical signals to improve communication between brain cells. Kernel refers to itself as a "human intelligence (HI) company"; Johnson, who has written that the combination of HI and AI will prove to be of great importance for the future of humanity, says his longterm objective is to improve both intelligence and quality of life as human lifespans grow longer.[33][34]
The industry has attracted investment from technology notables such as Elon Musk and Mark Zuckerberg. But some in the scientific community, noting the complexity of the effort and humans' limited knowledge of the brain, have questioned whether the effort will succeed.[10][35]
