What's something that's seen as Obsolete, but isn't?

Wrist watches. Extremely convenient, even when your phone is buried or you don't want to be distracted.
Yep. And it doesn't need to be charged every night like apple watch or similar.
Am looking for a new one if you have any recommendations.

Wii console: remote controler plus informatic knowledge make this a trustfull smartTV
I know, crazy right? The thing must be 20 years old now. Shows how versatile it is.

minidisc still seems futuristic to me.
I loved minidisc. It was just too late to the game with mp3s hot on its heels.

Buttons, knobs, plastic bezels.
At least according to the industry those are all in the past. The future is screens that go to the very edge of the device and absolutely nothing tactile.
And it is bullshit. It is less reliable, less convenient, less cool -- To say nothing of the safety disaster that nailing a tablet computer to the dashboard of every car has been.
Absolutely hate cars with those stupid big screens on the console. Give me buttons and knobs any day.

Tape drives. They're still used for backups/archival because they offer the lowest cost per gigabyte, as long as you don't need to access the data very fast.
Tape itself is cheap, but buying the other equipment for it costs a fortune.

Mediums matter. I think it's because a laptop or phone can sometimes be heavier and slower than a single post it or piece of paper. Just a thought though.

Can a CNC not do that for just the mechanical parts?
I know way too much about bootstrapping semiconductor production, which is viable but highly impractical.
Sure, but it's not as impressive (imo) when you also need a computer control system, a bunch of circuitry and electronics, and a whole mess of software to make it work in the end. A mill just needs enough spin and it runs exactly as intended.

Pretty much anything in a machine shop made in the last 80 years or so. So many people turn up their noses at anything that isn't computer controlled anymore. Yknow what a big old mill can do that a CNC can't? It can make every single part needed to make a new mill. It's a self replicating machine with the right know how. People don't respect that kind of quality anymore.
I don't think a mill can make the copper windings in the motor and isolate them.
Same with the power cable. -

Oh yeah, I have a copy of the Gingery books and I love it.
Gingery never really goes into how much power you need exactly, or what blend of RPM vs. torque is ideal. What would be your guess?

Everyone even tangentially related to healthcare is terrified of violating HIPAA in a way that leaves evidence that can be traced back to them. So the corps force dumb shit like this, while the employees are perfectly happy to tell all kinds of private health information to anyone who will listen. Especially if it's funny or gross.
Believe it or not, Canadian health services do this shit too.

Same with the power cable.You don't need an electric motor. You just need enough spin. I've seen old mills and lathes that run on steam. An electric motor just happens to be very convenient with our current technology.

Torque is the real limiting factor. You can always gear up or down for whatever you're working on, but at the end of the day you need enough torque to get the work done. And a proper milling machine needs A LOT of torque.

The email comes into their server unencrypted. They promise that they will encrypt it for you, though. Of course, you’re also relying on the sending server to keep the message secure as well.
Proton Mail's end-to-end encryption and zero-access encryption ensure only you can see your emails. Not even Proton can view the content of your emails and attachments.

Can you give me some typical values, maybe? That would be a big help.

There are no "typical values" when you're running a mill or lathe. You could look up "speeds and feeds", but that's really just a table that you plug into an equation to figure out how to set the machine. It all depends on what you're doing and what you're doing it with. Drilling a hole with a high speed steel drill bit is going to be a bit different than drilling it with a carbide spade, and all that is going to depend heavily on whether you're trying to run through titanium or tin. You need to fine tune running "x" bit through "y" material for a "z" sized cut.
Essentially, this is the knowledge that separates skilled labor from manual labor, and machining is (was, RIP cnc button pushers) skilled labor.

The vast majority of senders do not send email using end to end encryption. If you’re sending an email from a PM address to another PM address, sure, it’s end to end encrypted. If you’re sending to another service, it’s probably not end to end encrypted, unless you’ve both gone through the painful steps of setting up PGP encryption. Same as if you’re receiving from another service.

Im obsessed with tape storage, but for audio. Nothing more real than audio on tape! Luckily it's catching on again. Music is so disposable now, I hope we can keep physical formats alive and keep corporations away from it (digital offers them unlimited control over us).
