It’s really interesting to see nvidia make a play higher up the AI stack.
It really seems that generalist robots will be available in my lifetime. However, I have questions of their value. All of the demos look really slow, I do not think this is can be solved with more train data, but seems to suggest a current limit in the thinking- physical encoding and decoding of information and action, especially in humanoid robots which are a lot more complex
Owner of high-end hybrid EV.
Hybrids are still new to many car garages, which means skills to fix issues are not optimized.
It took 3 weeks and $9k to figure out my hybrid wouldn’t start due to a faulty basic EV component (fortunately under warranty).
In addition cost of fuel cell replacement pushes up cost and risk of ownership and can be common at 70-80k miles.
I hate to say it, but I am actually considering a trade in for gasoline.
Battery-only EVs have a much simpler drive train, and longer-lasting batteries.
Hybrids are not simply EV+ICE, they have very different kind of batteries (low-voltage, high C-rate).
In a hybrid, you have a battery that is 1/10th of the size, so the battery works 10x harder – needs to discharge at higher rate to move the car by itself, and usually there's no room for proper cooling of the battery.
In a BEV you have 10x more modules working at 1/10th of that rate, and there's battery management system keeping it at optimal temperature.
Batteries live longer when they're kept in 20-80% state of charge, and don't like to be cycled deeply. Small hybrid batteries get charged and discharged fully quite regularly, while the same distance needs only 10% of BEVs battery.
The form factor for these improves acceptance but no doubt there has been a societal shift, so much more of our lives are captured, shared, communicated and entertained through individuals filming. If not your peers, the generation below you is a ‘video and image as communication’ generation.
I own a pair and haven’t looked back. IMHO these have incredible utility and for me feel freeing. I have small kids and I want to capture those special small moments, but I refuse to pull out a phone to do so, small kids are so perceptive and they intuit something has changed when you pull out a phone to record. With the meta’s I just hit record and I don’t feel guilty or torn about recording. Granted, I don’t love how they look so I’m not always wearing them…
Seen some comments about juiced numbers, every teen interacts video first, that’s how they communicate with friends, not text, so I totally buy these numbers. Anecdotal, I’ve been to a couple of ray ban stores and staff say they sell like hot cakes and are sold out a lot of the time (obviously low production is a contributor, but point being they seem to have market fit)
I don’t know about the whole zone 2 thing, but I found running 10ks and pushing myself the whole time led to fewer gains than mixing slower paced runs with separate sessions of quarter mile sprints and 1 session of squats per week.
Also running extremely hard for a good distance for me at least, became mentally a lot less enjoyable
