Interesting to see the angry comments about how Digital TV fails more than Analog.
I don't watch TV so I dunno how is the situation in my country, but I did noticed when seeing broadcasts on public TVs (for example in bars and restaurants showing sports) that compression issues happen, decoding issues happen, and the whole thing is laggy, most obvious when you are seeing sports, during analog TV times, I would hear the cheers and fireworks after goals, victories and so on, all at same time, now I hear it staggered, with seemly poorer people cheering first, I assume because they have analog TVs and radios.
I still use an over-the-air antenna on a daily basis (and record from it using MythTV with ATSC tuners in a computer). The changeover from analog has been a bit of a give and take.
With analog broadcast, if you were a bit too far away you would still get a fuzzy image and sounds that had some interference with it. Now if you're a bit too far away the picture breaks up and the audio sounds like auto-tune. It doesn't take much of that to make it unwatchable.
On the other hand, when you get a solid signal the picture is amazing versus the standard-def of analog broadcasts. Add to this the benefit of multiple sub-channels on each broadcast channel and you get a lot more watching options.
I've installed an attic antenna and a pre-amplifier that supplies great signal to all coax (CATV) outlets in the house. That hardware cost what 1-2 months of cable TV subscription would have and that was years and years ago.
On balance the digital changeover has been much better in my experience.

I'm very surprised that Nvidia chips don't have memory size locked in hardware.
Doesn't that add manufacturing complexity? If you have multiple firmwares it's possible to flash the wrong one at the factory leading to a lot of pain if they get out to the market before this is discovered (your news 16 GB card is only using 8 GB of memory). This current scheme means there is one firmware to rule them all and the configuration of the hardware itself acts as the selector.

I have a Model 3 that is less than 2 years old. The build quality is terrible.
The side of my Model 3 trim on the inside just fell off for no goddamn reason. I don't even know how to fix it, it looks like the glue wasn't applied properly? This is on top of countless other problems that I've faced over the last 2 years.
It's impossible that Tesla is 3X the market cap of Toyota Why they didn't stop buying of Tesla the same way they stopped GME is criminal.
And they keep failing external quality tests and no one seems to care:

I don't have a Tesla, but I had upholstery on the backs of the rear seats (the part that becomes the floor of the hatchback when you fold them down) all off on my Ford C-Max. It looks like an adhesive failure there.
Not making excuses for the big T, just saying that there's a lot places for things to work out poorly in automotive.

I see four failures here on the part of tesla:
1) choosing that particular eMMC, likely not something specced for very high write endurance, or not speccing a larger amount of flash to spread the write endurance out over a period of up to 20, 25 years.
2) linux/operating system/software engineering implementation, for a certain volume of MB of writes per day, that would be known to wear out the flash write endurance over a short number of years. possibly a result of the software team not communicating properly with the hardware team. the software team very well may have been operating in a vacuum of assuming that they could do whatever they wanted within the CPU, I/O, RAM, and disk space limits of the architecture, and weren't even thinking at all of the consequences of their logging setup.
3) not making that a socketed/removable part.
4) asking the owners to pay for the replacement due to tesla's own screwup.
I mean, on your first point, it's an automotive grade part. I think any eMMC put under these conditions (75% full and the other 25% written heavily to with log files) is going to have a relatively short life expectancy.
What baffles me is that who is reading these logs? Can't they just turn then off (pipe to /dev/null) and then have cars that need troubleshooting put into a debug mode at some point?
I have one of these Stadia controllers and recently tried to play Cup Head (a notoriously hard 2d shooter) with it. I found the Bluetooth latency to make this unplayable. I would estimate it to be 2x or 3x the latency of a PS3 or PS4 controller. Anyone want to pontificate on whether that's a hardware limitation or a software implementation issue? (I was playing via Steam on Linux and tried all 3 controllers.)
