2026 will bring more blockchain/quantum/AI scams, hacks, overvaluations, bankruptcies; VC psyops, trolls and bots, paid articles and endorsements.
Meanwhile there wont be no...
- "AGI"
- useful/practical quantum computers
- meaningful blockchain use beyond tokenization
Like the past 10 years.

I was really thrilled to get to work on The WIRED Guide to Digital Opsec for Teens with @aumasson.jp. I think we did a good job but also apologies in advance to the teens that we tried to make jokes and generally Be Chill. Also no paywall to make it easier to share! www.wired.com/story/digita...

The International Association for Cryptologic Research has used heliosvoting.org – my online voting system – for a number of years.
This year, a trustee lost their secret key. The election has to be re-run.

As Apple expands its bug bounty, I spoke with VP Ivan Krstić about the significance + recent big swings like Memory Integrity Enforcement. These steps protect all users, but particularly those targeted by spyware: “We feel a great moral obligation to defend those users” www.wired.com/story/apple-...
Apple Announces $2 Million Bug Bounty Reward for the Most Dangerous Exploits
