Neural laces are a wireless brain-to-computer interface, essentially allowing us to have access to infinite knowledge. In 2015, scientists tested an early prototype with mice who were able to survive the implantation. Elon Musk has showed a lot of interest and announced on his Twitter that:

he is “making progress” on his neural lace design, which is designed to augment human intelligence and thereby avoid the inevitable takeover when A.I.s become smarter than us.
