Well, here’s my take on it:
You mention Neuralink. This is indeed big news. But is it biohacking? It’s being developed in a Musk venture. Not exactly a garage endeavour. Don’t get me wrong: it’s very exciting, but my point is, it’s already squarely in the commercial sphere before it’s even a reality.
The keyword in biohacking is “hacking”. That’s you, me and other enthusiasts trying to develop bodily enhancements without much help from academia or the medical world.
As such, we hackers are limited to what we can do safely. A few individuals like Lepht Anonym are crazy enough to try things that are borderline reckless. For the rest of us, what we can do is pretty much limited to implanting all manners of RFID / NFC transponders, and lifting or sensing magnets - for now.
The biggest news in that space is that it’s getting more and more democratic. But it’s not breaking news, Musk-style: it’s something that’s slowly taking off, and it’s still mainly under the radar. That’s why I bounced the question back at you, because I didn’t think you saw it from that angle.
A few companies like DT or IAR are making it possible for your average Joe to get an implant and enjoy an augmented human being’s life safely and on the cheap. Shmucks like me get to live their real, actual lives without keys, without passwords, or get to pay for things without a physical credit card, without risking life or limb. That’s newsworthy, just not spectacularly so.
Also, you’ll find that people who get “ordinary” implants suddenly find themselves to be very creative with what interfaces with those implants. As a result, if you dig around on the internet, you’ll find a lot of open-source software and hardware designed for implantees. That too is rather low-key, but it’s taking off alright. You just don’t get to hear about it because it never makes the headlines.
There are a lot of augmented humans and a lot of solutions for augmented humans out there. Many more and much more than meet the eye. They never make the news but it’s a big thing: what ordinary people from all walks of life do today is a lot more than what Kevin Warwick did in the 90’s, that was splashed all over the news back then. Now augmenting oneself is almost mainstream. That’s rather transformative in my opinion.
