show this to someone frm the 1950s
One day, transistors will cause this:
A fridge doesn't need AI. Or a firmware.
Or a firmware.
So are we moving back to bi-metallic thermostats?
Imagin not understanding material science and thinking it's a sort of slam dunk.
Remember when there was just a little dial in the top of the fridge, that you turn, from "cold" to "colder"? Yeah. That's really all that's required. Fancier fridges had more than one dial, that controlled individual compartments, like your crisper drawers.
I'm pretty sure technology connections has spent an hour explaining why that's sub-optimal while also explaining the refrigerant cycle for the 10th time.
Given the fact my fridge regularly freezes my water, I'm reasonably confident that the bimetallic strip would possibly do a better job.
There's plenty of middle ground. We had integrated circuits embedded in circuit boards for a long time before re-programmable chips started appearing, and those ones certainly didn't connect to the Internet and brick themselves.
PICs are cheaper than discrete ICs, even if they're programmed only once and shipped. This is why you'll see mainboards with un-populated sections - the processor has a software build that either excludes the un-populated parts or is designed to detect and ignore them. A discrete IC would need far more engineering to be able to selectively ignore, or each model would need it's own discrete IC.
If by discrete ICs you mean custom logic baked into silicon, yes that's always been expensive. I was referring to off-the-shelf ICs that cost pennies, which used to be orders of magnitude cheaper even than PICs (in the days before Internet connected fridges).
Before the term software engineer was commonplace, electronic engineers used design circuits around off-the-shelf components, like the venerable TI 555 timer or op-amps, and design a circuit around them. To do it they'd need the datasheets (https://www.ti.com/lit/ds/symlink/lm555.pdf). Hobbyists and aspiring young engineers would buy books like this: (https://www.computinghistory.org.uk/det/14021/IC-555-Projects/), which were like O'Reilly cookbooks for electronics circuits. The equipment to program a PIC used to be way beyond the reach of hobbyists, and wasn't necessary for manufacturers producing simple control circuits. If you look at circuitboards from that time you'll see some ICs with pins that aren't connected to anything because those just weren't needed for the circuit, much like you describe the empty sockets in modern boards.
It absolutely was possible in the pre-Internet days to design a fully functional fridge, and more, without writing code of any kind, and it was cheap too.
Why not? I'm sure we can easily make good ones at this point.

If I'd like emojis I'd use the clown emoji now.
I'll do it on your behalf so that it's used, but that you don't have to say you used an emoji.
🤡
Thanks! Handshake Emoji
Oh, and don't go through my history, I think I used an Emoji somewhere.
Lock me up. Try it.
Oh, so you like being locked up? 😏
It's a fridge. It doesn't even need an 8 bit microcontroller from the 1970s.
My washing machine keeps asking to be connected to the WiFi. 2 years I've been ignoring it, which has been very convenient. I think it just wants to watch porn.
Sock puppet porn.
So that's what it means when it asks for a full load...
Plus it keeps collecting socks. Pervert.
Your fault for putting socks and panties in the same load....
I caught my mother's dehumidifier connecting to WiFi to watch porn. The damn thing was actually dripping wet.

Y'all remember when Windows updated their OS and all computers without enough memory to run it were bricked?
Because we didn't throw a fit then, when a company's update destroyed our possessions, now we're getting more of it.
This could actually just be more modes of planned obsolescence.
Uhhhhhhh too many times to count, yeah. Which incident are you referring to?
And here I am using the same fridge that's been going since before the end of the Cold War.
Old fridges do last longer, but from what I understand they use significantly more energy to run.

Half of my homes appliances are from the 70s/80s, and a handful are modern. Can u guess which ones are breaking? Fuck I will NEVER get rid of my cooktop and oven they are older than me and will likely outlive me still !
Appliance repair guy here and I have only one thing to say: 😂😂😂😂😂😂😂
"Mourn" is a strong word here, but also, this is why you don't connect your fridge to the internet...
Time for me to get on my Samsung soapbox, and it is for an entirely different reason but very relevant for why you shouldn't buy a Samsung appliance!
Never. I repeat NEVER, buy a Samsung home appliance. For this reason ONLY. Especially when it comes to food preservation… or simply keeping food cold.
Here is the thing. Samsung will not let approved service repair companies stock parts. I repeat, WILL NOT LET APPROVED SERVICE REPAIR COMPANIES STOCK PARTS. So if you buy a Samsung refrigerator through Home Depot… and it breaks under warranty… you will get an apologetic service technician that will confirm that your appliance is broken.
Great!… I already knew that. That's why all of my perishables are starting to smell funny. The service person feels bad for you but they don't have the part to fix your appliance. They can order the part within 24 hours and be back this time tomorrow. Did you already have to take the day off work for the 6 hour service window???
Well this is all super annoying especially if you bought the EXTRA large capacity refrigerator and freezer… that NO ONE has enough coolers and ice to preserve…
Okay, so the service person orders the part and, dang… that wasn't the problem!
Weird, Okay so NOW the service person will order the more expensive part that is actually the problem. All of the ice in the cooler has melted. All of your cooler food has spoiled.
The refrigerator THREE DAYS LATER is now fixed. F#*k Samsung appliances. And this is the annoying part about all their 5 star reviews. Yeah they look nice when you give them their stars but their reliability is GARBAGE!!!
If an "appliance company" will not let service people stock parts… for the love of god DON'T BUY IT.
Lastly… Samsung ice makers ARE THE WORST!!! You will only have REGRETS. REALLY!!!!!!

Just wondering, is it confirmed that food actually spoiled? Because making the actual cooling dependent on smart functionality seems incredibly stupid. I assumed it would just be all the smart features that stopped working, but if it couldn't even cool anymore... woooow XD.

Wait, so there's not even a hard thermo in it to fail safely? Well done guys, you really saved 10p per unit on that one
.......a smart fridge should be smart enough to still act like a fridge when its confused
Yeah this is a matter of making it fail safe. A refrigerator that isn't operating at food preservation temperatures (and freezing temperatures in the freezer) is dangerous.
Appliances related to safety such as refrigerators and temperature control need to have a safe position they can fail to when their logic is confused.
