Of course, such an operation would typically be done by a hedge fund or private equity firm. But guess who is responsible the one of the world's largest hedge funds [1] with $200B+ AUM...
Tesla has shipped their custom SoC in every new car since April 2019.
Even then, the throttling on the Air seems pretty minor. About ~30% drop in performance after it levels off, which takes several minutes. Less if you get one of those pads with a fan in it that blows on the case.
Nevertheless, IHME was kept in the spotlight by the government and media because they deemed the experts as an independent health research center at a reputable university. Their predictions drove many poor policy decisions, culminating in the infamous claim by Trump that the pandemic would be over soon after Easter. Many epidemiologists, statisticians, physicists, mathematicians etc. called their conclusions into question and built better models (mostly using SEIR / SEIS). It took several more months for IHME to improve their own model, but by then the damage was already done.
I remember walking to one of those companies for a job interview and seeing someone pooping in broad daylight on the 8th and Market intersection. Not a great first impression.
Today the same engineer at a FAANG would make about $300k. Houses are about $2M and interest rates are about 2%, so relatively speaking things are cheaper. However, unlike in 1993, today's salaries are unlikely to grow by 10x over the next 30 years while the mortgage is paid off!
Compare this to a design like AVX/AVX2 that has wider 256-bit vectors, but almost always forces the programmer to treat them as two 128-bit vectors glued together. All because Intel realized they had to power down half of each vector ALU to save power at idle.
Of course, the future is hopefully more flexible vector ISAs like SVE. AVX-512 is not too bad either today, but Intel seems almost pathologically opposed to making forward-looking decisions (what about when they want to double the vector width again??).
Case in point is the Samsung Exynos M3, which despite its 6-wide decoder is barely competitive with the 3-wide ARM Cortex-A76. The Exynos would fare very poorly against any recent 4-wide Intel or AMD CPU.
The crazy thing about the M1 is that every structure in the CPU is huge - the decoders, the ROB, the number of execution units, even the caches. And apparently all of it is implemented very efficiently.
Meanwhile people do have serious issues with sleep even on Intel Macs running MacOS and Thinkpads running Windows. For whatever reason PC chip / hardware vendors just cannot get sleep to work properly. Apparently the problem is so low-level that even a company like Apple cannot paper over the problems without throwing out Intel entirely and using their own SoC in the new Macbooks.
Nevertheless, with the benefit of hindsight, it was likely the wrong decision from both a financial and strategic viewpoint. It's the kind of wrong decision Mark Zuckerberg avoided when Facebook bought Instagram and WhatsApp (despite being ridiculed at the time). Over the next decade, Tesla will likely be one of the most serious threats to Apple's dominance in high-end consumer tech goods (the other being companies working on AR/VR).
