The Deepest Deepfake of All

The interviewer asked, "Is that image real"? There's no way to tell. "What about this video?" It's hard to say. "You can't tell if that's real or fake either." No. Not without analyzing it. "Well, what about the prose? Did a human write this sentence?" It's possible, but it would not surprise me to learn that it was machine generated. "What about the voice in the video?" It's sonically perfect. I'd say 60/40 it's a machine, but I'd need to hear a few more sentences to be sure. "So, what you're saying is that I can't trust my eyes or my ears?" Yes. That's what I'm saying. "Is this the end of truth?" Continue Reading →

Fixing Facebook

Facebook Broken
If you were Mark Zuckerberg and you wanted to get ahead of potential government regulation of your business, what would you fix first? Would you try to curtail social media addiction, protect privacy, reduce mental health risks, reduce weaponized information, eliminate hate speech, flag misinformation, deal with data governance, or address some other seemingly intractable problem? Here's what I'd fix first. Continue Reading →
Crypto Regulation
China has declared all financial transactions involving cryptocurrencies illegal and is issuing a nationwide ban on cryptocurrency mining. Does this make crypto illegal in China? Not exactly. What does this mean for the crypto markets worldwide? What about the US? How will US crypto be regulated? Are cryptocurrencies considered securities? What about other digital assets? Welcome to the crazy, confused world of crypto regulation. Continue Reading →
Amazon Sidewalk
If you have an Alexa-enabled device or any Amazon device that is Amazon Sidewalk-capable, you are automatically opted in to sharing up to 80Kbps (capped at 500MB per month) of your WiFi network with Amazon and your neighbors. After I tell you how to opt-out, I'll tell you what it is and why Amazon thinks it's a good idea. If you want to use the service and lend part of your WiFi network to Jeff Bezos, you don't need to do anything. You are opted-in unless you do the following. Continue Reading →

Encrypting Your Crypto

Ledger Nano S
The moment comes when you realize there's real money in your crypto wallet and you start wondering about hackers and ransomware and all kinds of bad stuff. If you've set up a digital wallet, bought some crypto, and collected a few NFTs and you're starting to trade across a range of marketplaces and exchanges, you are starting to experience the exceptional financial freedom the world of DeFi has to offer. Of course, there's a catch… Now, you're also in charge of guarding the treasury. Continue Reading →
Merkle Tree
As she approached the entrance to the club, she gave the frame of her new prescription AR glasses a gentle squeeze. When she got to the door, it appeared to turn green, indicating recognition that she was over 21 years of age. Then, a message appeared along with a friendly voice asking for the 5 ADA cover charge. She shook her head yes. A moment later, the door opened, which indicated that the transaction had cleared. And so begins a story about life in a trustless, decentralized world − a tale from under the Merkle tree. Continue Reading →
ETH
We’re in the middle of a cryptocurrency bubble and an NFT (non-fungible token) craze. For context, the price of a Bitcoin (BTC) is bubbling around $56,000. The price of an Ether (ETH) is just over $1,700. That sounds bubbly, but this column is not about financial advice. I’m going to teach you, step by step, how to build a very small cryptocurrency mining operation so you can get a deeper understanding of the process. Continue Reading →
There's a reason you're getting more robocalls now: due to the pandemic, many international call centers were shut down. At the same time, the government did its best to reduce COVID-19-related phone scams. All that's over now. Robocall volume is back to pre-pandemic levels, and about 60 percent of these calls are scams or unsolicited telemarketing. Continue Reading →

Safe and Unsafe

safe and unsafe people
As the pandemic enters its second year, we're approaching an inevitable bifurcation of our society: "Presumed Safe" (those who have been vaccinated or exposed to the virus), and "Presumed Unsafe" (those who have not been vaccinated or have not been exposed to the virus). Two distinct groups that are going to test us in ways we've only read about in history books. Continue Reading →
Online Meeting
The speed of information is directly equated to economic success. If you learn something before your competitor does and you have the tools to make the knowledge actionable, you are almost always going to profit from it. So, while it’s true that “knowledge is power,” the true power comes from the speed with which you can create information asymmetry in a transactional environment. This is the goal of our new online innovation briefings. Continue Reading →
