🧠👁️ Elon Musk says Neuralink can make blind people see again, with a brain implant that skips the eyes completely.

🔌 It's called Blindsight. Instead of fixing the eyes, the implant is designed to write signals straight onto the visual cortex, the part of the brain that builds the picture you see.
🐒 Musk says one monkey has had a visual implant for three years.
🔭 Early vision is expected to be low resolution. Long term, Musk claims people could see in infrared, ultraviolet and even radar.
🏛️ The FDA gave Blindsight Breakthrough Device designation in September 2024: www.reuters.com/business/healthcare-pharmaceuticals/musks-neuralink-receives-fdas-breakthrough-device-tag-brain-implant-2024-09-17/
⏳ Musk says it's ready from an engineering standpoint and is waiting on regulatory approval.

Context & limitations

A breakthrough designation speeds up review; it isn't approval, and no human has a Blindsight implant yet. Use the prompt below to separate the evidence from the promises.

Do this yourself

Help me understand how close a medical-technology claim is to reality. The claim I want to check is ___ (for example: "Neuralink's Blindsight will let blind people see again"). First, find the original sources: the company's own announcements, any regulator statements, and peer-reviewed papers or trial registrations. Give me the links and the date of each. Then list every separate claim inside the headline. For each one, give: 1. The claim in one plain sentence. 2. Who is making it (company, founder, regulator, independent researchers). 3. The type of evidence: founder prediction, animal result, regulatory designation, human trial, or approved product. 4. What that evidence does and doesn't mean. For example, explain what an FDA Breakthrough Device designation is, and how it differs from approval. Finish with: - A one-line verdict: demonstrated, in testing, or promised. - Three questions I should ask before believing the next headline about it. Use current sources and say where evidence is missing. Don't present a prediction as a result.

Medical-tech headlines mix regulatory steps, animal results and founder predictions. Sorting each claim by its evidence shows how close a device really is.
