Google specifically mentions industrial users in their introduction to web serial. Besides, it doesn't matter what it's "targeted" at, it matters what it can do.

Do you know why hobbyists program microcontrollers using virtual com ports? It's not because Adafruit and Sparkfun got together and said "hey, we need a hobbyist stack for programming microcontrollers!" It's because the various types of serial are widely used in industry, have been for forty years, and therefore are already built into everything, including pretty much every microcontroller.

Being able to flash the firmware on your Arduino or WLED controller from a web page is very convenient. Being able to flash the firmware on your walkie talkie, camera, voice controlled devices or mouse and keyboard also very convenient but maybe a source of genuine concern.

Google says the API is "for" educational, hobbyist (okay) and industrial (sounds like an awful idea) users. But people's concerns aren't about what it's intended for but what it could be used for.

Isn't much of the point here the cultural shove? Sure, there's the line-go-up stuff; but that doesn't explain the companies gutting quite profitable software development operations to shovel money at Nvidia for things that have no demonstrated ROI; if it were nothing personal, just business, the level of enthusiasm for taking on poorly characterized risk would not be as fervent as it is. It's absolutely about resentment of the human resources that has been running at least as long as the demonstration that it would actually take some shoving to get them all to come back to the office, likely significantly longer.

this api is about ports that everyday hardware (like e.g. mice and keyboards) hasn't used for decades

Nope. CDC ACM and virtual com ports are pretty common. Lots of industrial devices, equipment configuration including networking gear, cellular modems, etc.

Specifically to the OPs point, while Logitech seems to use a proprietary USB HID protocol, Corsair mouse and keyboard firmware and profile updates seem to go over CDC ACM. I would be very surprised if lots of other manufacturers don't also use it.

The consumer stuff is generally all USB and the ship sailed a long time ago on the browser having access to that.

Browser access to virtual com ports is more an issue for things like industrial control. Somebody is defininitely going to make their SCADA system web based for the "easy updates" and find out.

Still, the ship sailed on that one a long time ago with Chrome too, and more generally a long, long time ago when Google convinced us all it's a great idea for your operating system to download software off the internet every time you want to run something.

It's the significantly less common case, for some combination of a lot of high-visibility stupidity being lethal and lethal accidents being public in ways that the details of nonlethal accidents aren't; but destruction of gonads under sufficiently foolish circumstances qualifies a living recipient.

Airport landing lights can actually be extremely strange.

I live close to FRA port. Yesterday was a festival one side, and airport other side. So I walked around on the roof and filmed both sides.

Two planes coming in, then 3 then 4. The lights pop out of nowhere. Obviously it is just distance and eye sight and camera sensitivity ... but the visual impression is indeed: aeh? where did that suddenly appear from?

Not absolutely wrong but absolutely correct, moron. Name called. Why is it called "name calling" when I call you a moron? That is not a name, that is a honourific.

A 1C battery is a 1C battery, regardless of how large it is.
Yes. But the charge is not measured in Volts mut in Amper-Hours. Or for easier use: milli Ampere Hours, or mAh.

I can make you a single cell 1V "accumulator" (as battery has a slightly different meaning), with what ever total charge I want. Farking idiot.

I can make you one that charges from a damn 110V 20A outlet, converted to 1.1V DC: for a million of years to get full.

Stupid idiot. What was your name? Ah, stupid swillden ... wanted to name call you.

They already pretty much are. You have to do at least a little performative fretting about the risks, which spoils the enjoyment of pure cheering at the best crunching sounds; but there's no way we'd justify the level of recreational head trauma something like football produces if we didn't fundamentally regard the players as relevant only the the way racehorses are.

Indeed.

And wind does not cost much crop land, as the pillars of the turbines only use very little land.

Solar can be everywhere, it is only put on crop land: if all agree the land usage has to change away from crops - for what ever reason.

And putting solar on crop land only makes sense for large installations anyway. Most installations are on buildings ... and soon parking lots and so on.

Then again: the percentage of land any country uses as crop land is extremely low. If some usage is diverted away from that, there is usually a reason.

for years before anyone knew where on the map the Strait of Hormuz was.
I guess you underestimate the education regarding geography on the world.

Well, perhaps I over estimate it.

It is only relevant how much wind and solar did in Germany.

Because of nukes and such ... and Russia and gas and such ... and Hitler, of course.

AI video technology is still nowhere even remotely near just "click a button and take what it spits out". I don't know how to break this to anyone here, but you're not just going to go to some video generation site and turn out Woodnuts without extensive skill about AI video tools themselves and a wide range of traditional video production tools, and without spending weeks to months and significant financial expense on the project.

Even if / when this changes, video production is still always going to be limited by the human at hand. Most people's movie ideas, plotting, scripting, directing, etc frankly will be terrible. The slop in this case is the human, not the tool.

This has to be the most obnoxious demonstration of why open source software culture is the greatest impediment to mainstream adoption of open source software that I've seen in a while.

WebSerial is about USB. As far as I know it doesn't even support any other kind of serial port.
