Fire, the wheel, steel, engines, electricity, cars, planes, computers were all transformational technologies created by human intelligence. It’s hard to put AI in context as we’re on the cusp of exceeding the foundation of human progress.

@jbulltard1 Think about it this way.. the same $300k house today at 6% and a $380k house with a 4% loan have the same ~$2000 payment. The sticks and stones didn't get more expensive. It's been 20 years since we've had a home building boom, but that margin will summon it.

even 4% rates, the math does not make sense. This is an asset that appreciates less than 4% a year, anyone paying over that in interest will forever be underwater. Even the wiseasses acting like they're geniuses for a 2.75% rate, unless you're in some hot market, from here forth, you won't see that.

i don't even get how we resolve this housing crisis. If rates stay elevated and you get a mortgage at 6-7%, the amortization table says you should stay renting. If rates go lower then everyone is going to just raise prices as the demand explodes. Low rates will make things worse.

@dollarsanddata Awesome read! Great perspective how levels of wealth impact your life and the likelihood to reach each. Most people do not have higher ladder influences in their life and this book is a proof point for what is achievable.

The Wall Street Journal reviewed The Wealth Ladder and wrote: “Investors of all ages would benefit from reading Mr. Maggiulli’s book...” Surreal to read that sentence. Truly appreciate the recognition. wsj.com/arts-culture/b…

My daughter recently had an ear infection. Took her to the doctor, who prescribed an antibiotic. That doctor visit cost $244. My insurance covered $60, so we owe $184 out of pocket. I pay $556/month for family health insurance. Something seems broken.

What is the end game for AI? Let's say at maturity, every man, woman and child spends $50 a month for this tool? Sounds like cell phone providers, and if you aggregate the market cap for cell phone providers, it's under $1T. I don't get it.

Well - I have made the COMPLETE jump. ALL my putts are now hit heads up. Previously I was only putting heads up outside 15-20 feet. For those not familiar with heads up putting, you hit the putt while looking at the hole, not the ball. I finally got comfortable with heads up with the shorter distances and I am very pleased with how well I am hitting start lines AND controlling distance. My distance control on the lag putts also continues to improve. I still occasionally would catch myself thinking about length of stroke, or how hard to hit it on the lag putts, but now my approach is I simply pick my spot I am aiming at, and say to myself "just play catch to the spot". If you have not tried heads up, give it shot. Shout out to Sasho MacKenzie for his research in this area and for exposing me to this technique.

Micron Director predicts NVIDIA’s market share to fall to 50-60% by 2028 as hyperscalers use more ASICs and less GPUs in their workloads to optimize training and inference workloads.

Rihard Jarc@RihardJarc

A MUST READ INTERVIEW with a current Director at $MU on HBM & GPU/ASIC market ( $NVDA, $MU, Samsung struggles ): 1. The hyperscalers $AMZN, $MSFT, $GOOGL are achieving significantly higher GPU utilization rates than they had in the past years. In 2022 and 2023, the GPU utilization rates were less than 40% The ROI on that in terms of hyperscalers getting their investment back used to be 12-18months. Now, the utilization rates are 70%-80 %, and the ROI has accelerated to only 6-9 months. 2. When $NVDA's Rubin comes out, he expects even higher GPU utilization rates - 90%. With Blackwell next year, he expects the cost of training on hyperscalers to be in the $60-$70 per hour range and for inference, smaller cases to be in the $5-$10 per hour range. 3. The supply of $NVDA's H100 has dramatically increased. The shortage, in his view, has been reduced mostly because of $TSM, which has improved their 4nm yield a lot as the technology has matured and as HBM availability has been good. In his words, when it comes to HBM, we are now moving from »call scarcity« to »high-volume pricing«. 4. HBM has been almost 2X-2.5X year on year. Both SK Hynix as well as $MU first had yield challenges as the biggest problem is TSV technology (through-silicon via), because you have to put eight of these chips on top of each other. If you have to put 12 of these on top of each other the connection between them is the biggest challenge. Both $MU and SK Hynix have become very proficient in that area. He continues to see the pricing going up slightly on the ASP for HBM. 5. He gives the example of HBM use in B100. If you say eight-high stack, that's around $400-$500; if you're using five or six of those, that's around $2500-$ 3600. It is 30% of the GPU cost in most cases. 6. The reason why HBM capacity has caught up in his view is not because of Samsung, but because the TSV technology has matured, and both SK Hynix and $MU have converted most of their CapEx into expanding HBM. He thinks this year might be the last year where we have a scarcity. He thinks 2026 will be even better with availability. 7. The reason why Samsung has struggled with $NVDA's certification process is because of thermal issues. $NVDA B100 and H100 have very tight thermal margins because they're using more than 700W of power. Each signal requires eight Gbps per pin. 8. Samsung has been struggling with the DPPM rate (defect parts per million rate), as it is significantly higher on Samsung parts compared to their competitors. The second thing they struggle with is the eye diagram. The eye diagram is the margin, and according to him, that margin has always been poor compared to SK Hynix and $MU. The reason is that $NVDA uses NVLink. The poor margin also affects the data transfer. 9. According to him, it makes sense that $AVGO approved Samsung as they use less than 300W of power and have more margin, $AVGO uses four Gbps-six Gbps per pin, $NVDA uses twice that, both in power as well as data transfer rate. 10. He thinks that by 2028, $NVDA's market share will be reduced to 50-60% with most of it going to hyperscalers doing their own ASICs. He mentions $GOOGL, noting that their TPUs are at the forefront of this, as they have highly customized FP4 optimization for inferencing and have already deployed TPUs for Gemini, as well as for internal AI training. Second is $AMZN's with Trainium, while both $META and $MSFT are still a bit behind and need to catch up. If he had to make an educated guess, he thinks that $GOOGL and AWS are already serving 50% of their own internal inferencing with their custom ASICs.

These kinds of things are hilarious to me, if you're worth $4.6M and don't know how to work your money to where you can retire, you're just lazy. I could probably retire making $20k/mo w/ $1M if I wanted to. x.com/CDInewsletter/…
Canadian Dividend Investing@CDInewsletter

This week in the Globe and Mail a mid-40s couple with a $4.6M net worth (and an additional $446k coming as severance) were told they can't afford to retire. If they can't afford to retire, then *nobody* can. Anybody else absolutely exhausted with these nutty retirement takes?
