Terrible math is terrible.

Better napkin math that is still being unrealistic compared to the true costs of space-based datacenters: https://www.reddit.com/r/theydidthemath/comments/1quvbi4/sel...

Just contemplate what the radiator array and solar array needed a 1GW datacenter and all the cooling equipment and coolant, and imagine the harsh environment in space degrading it constantly.

The only point of the space-based datacenter idea is to pump the Spacex IPO

Sports are much more likely to result in injury, and as you get old, staying in the game (of life) is more important. It can take a long time to recover, if ever, from an injury as you age. I loved playing soccer, and did so until I was almost 50, but many of my issues, physically speaking, are from soccer. I loved doing it, and it is far more fun than strength training, but too many injuries result.

Strength training and controlled cardio is much better for continuous health.

Hyundai and Honda (especially Honda) have brought back more physical buttons in the past several years. The CRV especially has a great button/control layout. A big reason we went with the Ioniq 5 is due to the physical controls.

This easily could be AI generated, there is little character to it, and if you told me it was AI generated, I would believe you.

That's undoubtedly to detect frustration signals, a useful metric/signal for UX. The UI equivalent is the user shaking their mouse around or clicking really fast.

Our local Subaru dealership has an option to use an AI assistant when you call to set up an appointment. I tried it, it worked perfectly, better than a human, honestly. Likewise our local Taco Bell is uses AI ordering and it works great as well. I'm sure they have their issues, but I'm losing nothing by not talking to a human in this situation, and there's always a human available if I need one.

US automotive companies are backing away from EVs because they would have a huge impact on the automotive adjacent industries. They are more reliable and have little to no maintenance, whereas ICE cars prop up multiple billion+ dollar industries. We would spend far less on an automotive industry if we switched predominately to EVs, and so the existing industry is pushing back. End of story.

The "A" in AGI is for artificial, not advanced.

"100% AI-generated code soon" doesn't mean no humans, just that the code itself is generated by AI. Generating code is a relatively small part of software engineering. And if AI can do the whole job, then white collar work will largely be gone.

I swear some people are using some other tech than I'm using the past few months. Where I work, Claude Code is developing major changes to our very large code base (many repos, millions upon millions of lines of really important code) and pushing to prod regularly. Even the most bearish of engineers are now using it to ship important code daily. It still has issues and you have to know how to use it, but it is a shocking productivity increase (although Amdahl's Law applies for software engineering, too. Coding is only a relatively small percentage of what is done)

That's because there are fewer white men because white men (and women) are the ones that are returning from the Baby Boomer era. https://fred.stlouisfed.org/graph/fredgraph.png?g=1T9dv&heig...

I didn't prompt anything odd, just standard prompt "etiquette", actually I significantly prompted less than I would usually do, trying to do a simple prompt like you did.

I just tested this with Claude Code and Opus 4.6, with the following prompt:

"I have an arbitrary width rectangle that needs to be broken into smaller random width rectangles (maintaining depth) within a given min/max range. The solution needs to be highly performant from an algorithmic standpoint, well-tested using TDD and Red/Green testing, written in python, and not have any subtle errors."

It got the answer you ended up with (if I'm understanding you correctly) the first time in just over 2 minutes of working, and included a solid test suite examining edge cases and with input validation.

> Other than Microsoft nobody even makes decent laptops in the Windows world.

Strong disagree on this one - there are some great laptops available, they just aren't "macbook clones". I have an Asus Rog Strix that I love. Lenovo have great ones, Dell, even HP is back in the game somewhat.

I use a macbook professionally, but still don't like the keyboard very much. The display is good, but my Asus display is better. Aluminum is pretty, but I don't like the feel of it on my wrists.

New comment by gilbetron in "Jensen Huang says Nvidia is pulling back from OpenAI and Anthropic"

gilbetron — Thu, 05 Mar 2026 14:20:58 +0000

I think it is likely that they realize that LLM models will be able to be developed by many companies, and I see most early, heavy adopters of LLMs doing the math on giving OpenAI/Anthropic token fees versus just having in-house models, and realizing that, at this point, it sure seems like having your own models might be the future path.

Nvidia is in position, and has the resources, to see this with a much broader lens, and realizes OpenAI/Anthropic won't be able to corner the market and the long term play is to sell GPUs to cloud providers and companies themselves.
