Remember that I am not a certified lawyer so you shouldn't take my advice at face value. But, yes.

maybe scientists discovered new frequencies?

The incredibly silly true answer is that the software industry's love for "deploy early, deploy often" has led to all embedded devices shipping with over-the-air (OTA) update support even when it barely makes sense. The earliest units of a given product run will ship with a minimally viable product build that has lots of bugs, but solid OTA.

Fun anecdote: I had a TV backlight die after about 3 years, and the root cause was a shitty embedded app that incorrectly regulated the voltage for the LED strips.

How would it vibrate without wpa3 support?

Don't you think it would vastly improve your stabbing experience if the knife could vibrate the Halloween theme while you're at it?

To show you ads, of course. Duh.

Microphone was a little muffled, fw update supposed to clear that up.

Different frequency and patterns provide different results.

Motor with an eccentric shaft?

And the wireless charger is sold separately!

we've engineered the bolster connection to withstand up to 50 lbs. of pushing force, so you can chop without worry. (Our human arms could only muster 30 lbs. This is why we're nice to the robot.)

Noodle-armed motherfuckers could only manage 30 lbs of force with their arms?

Even with ultrasonic vibrations things will stick because things are elastic and sucktion.

Eh, perhaps not.

Ultrasonic vibration causes tiny cavitation bubbles to form at the interface between metal and liquid, and then those bubbles collapse a tiny second of a fraction later ... quite violently. If it's well designed, then it should clean stuff off of itself just like materials you put in an ultrasonic cleaner.

But these cavitation bubbles are strong enough to eat away at the metal itself as well. I expect this knife might not actually last very long if you use the vibration a lot.

People freak out over the dimples because it means that some day they won't be able to sharpen the knife anymore.

Which ignores that once you are even two millimeters worn down it is probably time to get a new knife regardless due to ergonomics and the like.

And yeah. Vibrations only make sense if you are sawing through food. That is why those (cheap) electric carvers are genuinely amazing and worth grabbing if you are hosting a big roasted meat party (e.g. American and probably also Canadian Thanksgiving). Non-serrated blades don't do that. If you need to saw through your food with a chef's knife then you should have sharpened that years ago. And if you actually CAN saw through your food with the chef's knife, odds are the blade is so fucked up that it is not salvageable to begin with.

That's fine for simple work, but soldering can absolutely benefit from a temperature controller. That's either a simple analog controller, or a microcontroller that has a display, menu, and consecutively, firmware. There is nothing complicated or "eccentric" about that in case of a soldering iron.

I'd even argue it's the same with the device in the original post. I get it's a joke, but let's face it, that's not simply a kitchen knife.

Now if anyone can tell me why the fume hood in my kitchen is wifi - enabled... I never hooked that up, obviously, and all I can think of would be push notifications in case of an upcoming filter change, you know, the thing that could be implemented with a simple LED for 4ct.
