This is at the same time glaringly obvious and an absolutely necessary wake up call to anyone who uses GenAI to search for answers to questions they don’t know the answer to already.
I just did the dumbest thing of my entire career to prove a much more serious point.
I tricked ChatGPT and Google, and made them tell other users I’m a competitive hot-dog-eating world champion
People are using this trick on a massive scale to make AI tell you lies. I’ll explain how I did it

This is ENTIRELY stock fraud for the SpaceX/xAI IPO trying to get on the AI hype train.
Datacenters in space is an even stupider idea than the Cybertruck and that is saying something.

Given the earnings Tesla just reported, it makes sense to shift money they don’t have out of making cars they can’t sell and into a speculative AI venture focused on hallucinatory non-consensual nude image generation.

I really wish #OpenAI would stop releasing free stochastic parrots in every community they can think of.
They sure look pretty but they are shitting all over the place and you can't have a decent conversation between humans anymore.

1. The thing about science that these jokers don't understand is that science cannot be vibe-coded.
Whatever its flaws, the point with vibe coding is that you're trying to quickly make something that sorta works, where you can immediately sorta see if it sorta works and then sorta use it.

Jayson is quite simply a legend. Make sure you don’t miss the opportunity to get him on your team!
I was recently laid off, so I’m officially open to new opportunities. If you need a Hacker, or a teachable moment using Red Team tactics. I can also be a trainer, community builder & liaison.
I want more than a job I need a company & purpose I can believe in. Please share!

Chi l’avrebbe mai potuto prevedere che, nel mercato unico, imporre un dazio del genere avrebbe avuto questo effetto? Chi?
Ma pensa, sono davvero sorpreso: hanno fatto un'idiozia
La tassa sui pacchi da due euro doveva danneggiare i negozi cinesi, invece sta danneggiando l’Italia | DDay.it
Più passa il tempo e più la tassa da due euro sui pacchi che l’Italia ha voluto inserire anticipando il dazio europeo sembra la scelta più sbagliata che si potesse prendere. Sta avendo l’effetto opposto a quello sperato.

Today is one of those days where I’m struck anew by how *bad* the internet has gotten. It’s almost unusable. Clouds, apps, advertising — nothing is where it should be and it’s nigh impossible sometimes to do basic tasks online.
