An analysis showing that my name has a strength of 297 in some popular AI models, pushing me into the top 20%. It also says: GPT-5.5 SAYS GERMAN NEUROSCIENTIST AND PSYCHOLOGIST KNOWN FOR RESEARCH ON PHANTOM LIMB PAIN, EMBODIMENT, AND VIRTUAL REALITY THERAPIES.
Highlights: ChatGPT has left a profound impact on people because of its incredible potential. Artificial intelligence will inevitably infiltrate and change every facet of contemporary life.
A post-mission summary showing that I received 20,000 points for fulfilling a mission, which WASNT EASY, plus zero bonus points that I could have gotten for doing a good job, minus almost a quarter million points for murdering people. I swear I was only aiming for armed personnel but apparently the game‘s rating isn’t having any of that. Fair enough.
WARUM FÜR DIESES BUCH KEINE KI VERWENDET WURDE Wie schon in der Widmung impliziert, wurde dieses Buch vollständig ohne die Hilfe von Large Language Models oder anderer generativer KI geschrieben, also ohne technische Hilfsmittel, die eigenen Text erzeugen können. Einige in der Wissenschaftskommuni-kation tätige Menschen stehen dem Konzept dieser Tools zumindest ein wenig offen gegenüber und sehen zum Beispiel einen Nutzen darin, wenn es um die Ideenfindung geht oder um die Zusammenfassung von langen Studien oder um das Finden einer treffenden Formulierung. Bei mir gibt es diese Offenheit nicht, und zwar aus drei Gründen: Die drei Pfeiler, auf denen die Wissenschaftskom-munikation aus meiner Sicht ruht, sind Korrektheit, Authentizität und Transparenz. Das bedeutet, dass Sie nicht nur möglichst fehlerfreie Informationen bekommen, sondern auch nachvollziehen kön-nen, woher sie stammen und vor welchem Hintergrund und mit welcher Einstellung sie verarbeitet und präsentiert wurden. Nur so kann die Wissenschaftskommunikation jemals eine sinnvolle Ver-trauensbasis schaffen. Das Problem: Bei allen drei Dingen fallen LLMs durch. Sie erfüllen nicht meinen persönlichen Anspruch, was Fehlerfreiheit an-geht, sie haben keinen menschlichen Kern, und sie sind nicht auf einen durchschaubaren Entscheidungsprozess ausgerichtet, können also nie wirklich transparent sein. Bei dem Buch, das Sie vor sich haben, ist das anders: Es sollten eigentlich gar keine Fehler darin sein - aber sollten sich dennoch welche finden, dann stammen sie zumindest ganz authentisch von mir. Und zum Zweck der Transparenz werden alle Quellen und Inspirationen genannt. All das bin ich Ihnen aus meiner Sicht schuldig.

For what it's worth, we are monitoring the real-time partial data and making them look pretty for you so it's easier to understand what's going on, so here is our first take. Hungary general election 2026 With 6.56% of votes counted 50% • Tisza 110| Fidesz-KDNP 71 Mi Hazánk Mozgalom 9 Undeclared 9 Source: NVI, Hungarian national election authority But, as I said in previous post, this is still very, very early days, so - just as with the polls earlier - don't read too much into it.

A LinkedIn post from my profile, reading: “It's a very simple equation, really: Science communication needs to be accurate, it needs to be authentic, and it needs to be transparent. If you're not doing it that way, you're not doing science communication at all. In addition, *good* science communication is inclusive, it's ethical, it's sustainable. If you're not heeding these things, you're not doing science communication right. Which is why I am profoundly shocked by ostensibly reasonable people promoting the use of chatbots for science communication. Their use decreases factual accuracy. It decreases transparency. It decreases authenticity. Those things are true regardless of *which* chatbot you're using and regardless of *how* you're using it. Plus, the tech is not sustainable, not inclusive, not ethical. The promotion and use of Al chatbots is already damaging science communication and, if taken to the extreme, will be capable of quickly destroying it. Not through the rise of evil Al, but through ignorance on part of the users, rapidly destroying the trust that science communicators have been able to build over decades. Everything I will ever publish will be written by humans, and by humans only. If science communication goes the way of the robots, it will go there without me.”

Based upon a very productive meeting that I have had with the Secretary General of NATO, Mark Rutte, we have formed the framework of a future deal with respect to Greenland and, in fact, the entire Arctic Region. This solution, if consummated, will be a great one for the United States of America, and all NATO Nations. Based upon this understanding, I will not be imposing the Tariffs that were scheduled to go into effect on February 1st. Additional discussions are being held concerning The Golden Dome as it pertains to Greenland. Further information will be made available as discussions progress. Vice President JD Vance, Secretary of State Marco Rubio, Special Envoy Steve Witkoff, and various others, as needed, will be responsible for the negotiations — They will report directly to me. Thank you for your attention to this matter!
So what must be done? First, accept reality. Under Trump, the United States can no longer be treated as a reliable ally. This is not hostility towards America; it is contingency planning. Defence ministries and chiefs of staff should be war-gaming worst-case scenarios - including the previously unthinkable: US aggression against a Nato ally. Not doing so would be a dereliction of duty. Second, Europe and Canada must stand together without hesitation or ambiguity. There must be no daylight between them. Tariffs, threats and intimidation succeed only if they divide us. Unity is deterrence. Third, Nato must be Europeanised - not dismantled, but rebalanced. Nato already has the command structures, doctrine and interoperability to function. What must change is dependence. For decades, Europe outsourced its security to Washington and spent the dividend elsewhere. That era is over. Defence spending must rise - now, not in vague promises a decade hence.
