Neuralink's first human trials are underway. Synchron's stentrode has been implanted in over 10 patients. Kernel's Flow headset reads cortical activity non-invasively. We are at the iPhone 1 moment of brain-computer interfaces.
BCI bandwidth has doubled approximately every 18 months since 2015. At current rates, we will reach 1 Mbps neural read speeds by 2035 — enough to decode imagined speech in real time. By 2040, 10 Mbps will enable full-sensory neural rendering.
"The keyboard will be remembered the way we remember the telegraph: a revolutionary invention that was rendered obsolete by something unimaginably faster."
Keyboards. Mice. Touchscreens. Voice assistants (why speak when you can think?). Passwords (neural signatures are unforgeable). Programming languages as we know them — direct intent-to-code translation eliminates syntax entirely.
Telepathic communication. Direct knowledge transfer. Collective consciousness networks. The boundary between human and machine cognition dissolves not through AI becoming smarter, but through humans upgrading their I/O bandwidth.
