The Interface Age

A practical map of how neurotechnology works, where it already helps, what still breaks, and who is building it.

Read the field guide

What it covers

• How neural systems read, write, and close the loop
• The trade between signal quality and surgical burden
• Sixteen company dossiers with linked evidence
• Use cases that already work in people
• The research, timeline, bottlenecks, and likely next steps
• The labs, device makers, regulators, and payers behind the startups

The short version

Neurotech already works. People can move cursors, enter text, reduce tremor, and recover pieces of vision.

What is still missing is a system people can rely on for years. Durability, calibration, surgery, reimbursement, maintenance, and privacy now matter as much as the signal itself.

Built with

The site uses semantic HTML, custom CSS, and vanilla JavaScript. There is no framework and no build step. GitHub Pages handles deployment.
