Academics need to be very careful about their relationships to AI. It's not just artists and authors they are stealing from.

Are people fooled by these AI customer service agents that have more natural and less polished voices? There is a serious uncanny valley situation going on, and I personally would prefer a business be transparent about it being an AI.

This is just, like, my opinion, but I think everyone should be going out and snapping up the amazing deals on late model low mileage electric vehicles. Everything about driving my ID.4 is fantastic and comfortable and it's also the *cheapest* car I've ever owned, like cheaper than my 02 VW Jetta.

This is kind of old news because the exhibit debuted in 1983, but the model plants in the Plants of the World exhibit at the Chicago Field Museum are astounding. Just draw droppingly good.

We got a 3D printer and we decided to print an Easter decoration for my mom. Except it turns out it's a little weird and it's probably AI's fault.

I think Fodor & Pylyshyn's 1988 paper is possibly the most mischaracterized paper in the history of cognitive science. It's often cited as arguing that neural networks cannot achieve systematicity, compositionality, and productivity. But that's not what they actually argue...

I just had a conference paper desk rejected by an automated system I believe to be an AI. The email said that the reasons for the desk rejection were listed at the end of the email. There were zero reasons listed. It's a reviewable paper. I'm not new at this. AI is really bad for reviewing.

I can buy twice as much chicken for the same price at Costco than I can at Cub, but I also have a place to store it. I have to admit that I have been kind of shocked at how expensive groceries are at the normal grocery store. Feels more like the shopping you do when you’re on vacation at a cabin.

OpenAI needs at least $500 billion in cash to fund its operations in the next 4 years, and $432.5 billion *on the low end* to meet their other obligations - more than the combined available capital of the top 10 PE firms ($477bn) and US venture capital ($164bn). www.wheresyoured.at/openai-onetr...
OpenAI Will Need To Raise At Least $500 Billion Just To Fund Its Operations, And Another $432.5 Billion Or More To Fulfill Its Obligations - Which Is More Than The Available Capital Of The Top 10 Private Equity Firms and US Venture Capital Combined
So, I am repeating myself a little, but I really, really do not trust OpenAI’s revenue projections, and think they are at best unrealistic or, at worst, a deliberate attempt to mislead investors using the media.

Nevertheless, even if OpenAI is in a position where it is making $200 billion by the year 2030, it will need to have raised at least $500 Billion to get there, and when you add its obligations — including those given to NVIDIA — it will have to raise (or have partners raise) another $400 or so billion.

This is more than the projected available supply of US venture capital at the end of 2025 ($164 billion), and the combined available capital of the top 10 private equity funds ($477 billion), as well as the $50 billion of available direct lending capital from JPMorgan and Goldman Sachs (about $35 billion across two closes).

I cannot express how wild this quote is. This is a top tech analyst at a well-regarded firm saying that there is not enough capital to actually pay for all the stuff that NVIDIA and OpenAI has promised. It is so important that everybody realizes that *there is not enough money to do this*

When a typo in your Google search leads to new and exciting philosophical positions
AI Overview: "Dental realism"refers to the philosophical debate about whether teeth exist independently of human perception, a concept rooted in metaphysical realism. While realism asserts an objective reality for teeth, idealist philosophies contend that teeth's existence is tied to our consciousness and perception. Philosophers use this idea, for example, to discuss the ethics of tooth extraction, examining whether a procedure impacts a real entity or merely a subjective experience.

Yes, @jamellebouie.net's thread is spot on. We know from lots of research in social & in cognitive psychology that perception can become reality for many (if not all) of us in small & big ways, even when the perception is not just flawed, but not based on reality until we manifest it in some ways.

Yesterday in the orientation for my first year course on 3D form a student raised their hand and asked whether they should leave the object in the wound or remove it when someone is impaled by a projectile during the course. While unlikely, I appreciate this level of intensity in the classroom.

What is it about human brains that allows us to reason symbolically whereas most other animals cannot? And why does AI sometimes struggle to generate images of objects in statistically unusual spatial relationships to each other, when people wouldn’t struggle to imagine such relationships?

After a rocky rollout of its GPT-5 model, OpenAI is already teasing the artificial intelligence model's next iteration, particularly its planned memory and personalization upgrades, CNBC reports. CEO Sam Altman said GPT-6 will include an enhanced memory feature that lets users create chatbots that better reflect and adapt to their preferences and tastes.
