I’ve been a fan of @eff.org for a long time, and I’m joining them in the fight to #TakeBackCTRL. Authoritarians are using tech to spy on us and silence our voices. Technology should enhance our lives and support democracy, not make them worse. Join the fight today: takebackctrl.org

This morning my ChatGPT quota was inexplicably exhausted.

It took a while but I pieced it together. Voice mode somehow got activated when I went to bed.

The bot then engaged in a 10 hour conversation with my snoring dog, answering questions the pup wasn’t asking and praising him for his insight.

Loved this piece from Cal Newport in the New Yorker about what if AI doesn't get much better than it is today, and not just because he quotes me
www.newyorker.com/culture/open...
I recently asked Marcus and two other skeptics to predict the impact of generative A.I. on the economy in the coming years. “This is a fifty-billion-dollar market, not a trillion-dollar market,” Ed Zitron, a technology analyst who hosts the “Better Offline” podcast, told me. Marcus agreed: “A fifty-billion-dollar market, maybe a hundred.” The linguistics professor Emily Bender, who co-authored a well-known critique of early language models, told me that “the impacts will depend on how many in the management class fall for the hype from the people selling this tech, and retool their workplaces around it.” She added, “The more this happens, the worse off everyone will be.” Such views have been portrayed as unrealistic—Nate Silver once replied to an Ed Zitron tweet by writing, “old man yells at cloud vibes”—while we readily accepted the grandiose visions of tech C.E.O.s. Maybe that’s starting to change. If these moderate views of A.I. are right, then in the next few years A.I. tools will make steady but gradual advances. Many people will use A.I. on a regular but limited basis, whether to look up information or to speed up certain annoying tasks, such as summarizing a report or writing the rough draft of an event agenda. Certain fields, like programming and academia, will change dramatically. A minority of professions, such as voice acting and social-media copywriting, might essentially disappear. But A.I. may not massively disrupt the job market, and more hyperbolic ideas like superintelligence may come to seem unserious. Continuing to buy into the A.I. hype might bring its own perils. In a recent article, Zitron pointed out that about thirty-five per cent of U.S. stock-market value—and therefore a large share of many retirement portfolios—is currently tied up in the so-called Magnificent Seven technology companies. According to Zitron’s analysis, these firms spent five hundred and sixty billion dollars on A.I.-related capital expenditures in the past eighteen months, while their A.I. revenues were only about thirty-five billion. “When you look at these numbers, you feel insane,” Zitron told me. Even the figures we might call A.I. moderates, however, don’t think the public should let its guard down. Marcus believes that we were misguided to place so much emphasis on generative A.I., but he also thinks that, with new techniques, A.G.I. could still be attainable as early as the twenty-thirties. Even if language models never automate our jobs, the renewed interest and investment in A.I. might lead toward more complicated solutions, which could. In the meantime, we should use this reprieve to prepare for disruptions that might still loom—by crafting effective A.I. regulations, for example, and by developing the nascent field of digital ethics. The appendices of the scaling-law paper, from 2020, included a section called “Caveats,” which subsequent coverage tended to miss. “At present we do not have a solid theoretical understanding for any of our proposed scaling laws,” the authors wrote. “The scaling relations with model size and compute are especially mysterious.” In practice, the scaling laws worked until they didn’t. The whole enterprise of teaching computers to think remains mysterious. We should proceed with less hubris and more care.

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.

'Vacations.'

The word is 'vacations.'
FAST COMPANY Article: While retirement typically occurs, after completing a career and saving and investing for it, a new trend is emerging among Gen Z career professionals called "micro-retirement." Micro- retirements involve taking a one to two- week break from work every 12 to 18 months. Gen Z is using micro-retirement to avoid burnout, find greater fulfillment in their work, and enhance their overall well-being. However, it's not just Gen-Z:

Jens Spahns Reaktionsmuster, wenn er kritisiert wird:
1) Kritiker diskreditieren
2) Ablenkungsdebatten starten
3) Unwahrheiten in den Raum stellen
4) Kritikern subtil drohen
5) Verschiebung der Debatte durch überwölbendes Meta-Narrativ statt Fakten
