I kinda think the way people use ChatGPT is sort of aspirational because it seems to emulate the way rich people have sycophants lying to them all the time until they lose touch with reality and also their entire minds

Substack aims to become a main publisher of news and information in the 21st century, which would give the company tremendous power to tilt the political discourse toward far-right politics. www.theframelab.org/why-framelab...

There is no power on earth for authors like word of mouth. Especially with the death of Twitter, so many of us have lost huge chunks of our reach. So please, if you love a book, tell your friends and talk it up on your social media. No voice is too small, every single word counts. And thank you!

Again, the revenue they are sharing w/ Nazis is money YOU spend on your fave substackers. If you're accepting paid subscriptions on substack— and putting content behind a pay wall—you are inherently asking your readers to share that money w/ Nazis. "You can't read this unless you give Nazis money."

Stand by this: www.politico.com/newsletters/...
What’s a technology that you think is overhyped?

I’m going to give a sideways answer to this, which is that the venture capital business model needs to be understood as requiring hype. You can go back to the Netscape IPO, and that was the proof point that made venture capital the financial lifeblood of the tech industry.

Venture capital looks at valuations and growth, not necessarily at profit or revenue. So you don’t actually have to invest in technology that works, or that even makes a profit, you simply have to have a narrative that is compelling enough to float those valuations. So you see this repetitive and exhausting hype cycle as a feature in this industry. A couple of years ago, you would have been asking me about the metaverse, then last year, you would have asked me about Web3 and crypto, and for each of these inflection points there’s an Andreessen Horowitz manifesto.

It’s not simply that one piece of technology is overhyped, it’s that hype is a necessary ingredient of the current business ecosystem of the tech industry. We should examine how often the financial incentive for hype is rewarded without any real social returns, without any meaningful progress in technology, without these tools and services and worlds ever actually manifesting. That’s key to understanding the growing chasm between the narrative of techno-optimists and the reality of our tech-encumbered world.

Clearly there cannot be "one way to do product management." I, myself, organize PM into six fundamental flavors, as shown in this diagram (note the labels along the legs of the triangle). Full post: sociotechnical.org/archive/six-... [1/9] #productmanagement

The problem, ultimately, is that people seem to think categories are real things, things that exist in nature. And they aren't. NATURE exists in nature. Any finer distinction is something that we draw - and we have to decide where to draw it.

“Infection with the coronavirus is known to leave behind a long legacy of health problems, many of which are characterized as long Covid. But mounting evidence suggests that the coronavirus also befuddles the immune system into targeting the body, causing autoimmune disorders in some people.”
