Yes, and in the world of real products, requirements keep changing. And
if the product has a million lines of software and you change a few
thousand of them and recompile, I wouldn't call that writing a new
program. If you publish a novel and then fix some typos in the second
printing, I wouldn't call that writing a new novel. And if you fix some
errata in a chip, well you see where this is going. I suppose from the
fab perspective it's a new chip, but from the design perspective it
isn't. There's millions of lines of VHDL and you change a few.
And you constantly optimize and tweak stuff even if the requirements
don't change. Do you seriously think today's 555 timer is made from the
same masks as 50 years ago?

I'm interested in seeing it. I'm not going crazy searching for it but
I've looked around a little bit and not found much. I'm not the one
making claims. I've expressed skepticism to your claims. I'm open to
being convinced by evidence.

My coffee maker has no timer, but I use a rice cooker with a setup like
that, and it doesn't seem all that cheap. The buttons and display are
fairly large. Its marketroids also like to claim that the software
inside it is sophisticated, though idk what it is really doing. It
supposedly uses "fuzzy logic" to figure out how to cook the rice more
consistently than a traditional thermostat cooker would.
I also have a pressure cooker that has a timer but no digital clock. It
has quite a lot of buttons for cooking different kinds of stuff (soup,
grains, etc.) though afaict they really just run the cooker for
different amounts of time. So the extra buttons aren't really all that
necessary and if they cared about the $.01/button they could have just
left them out.
As mentioned, AvE took one apart and IIRC he found an 8 bit MCU inside,
but I would have to watch the video again. They do have more expensive
models with clocks so I guess they saved a few cents by leaving the
clock out of mine.
How about a temperature controlled soldering iron, is that simple
enough? This one has a 32 bit cpu and multitasking OS:

Yes, and so far you have consistently failed to put up any numbers that
have any convincing connection with reality.

I remember mention of the MARC4 but didn't realize it was programmed in
Forth. That is interesting and I'll see what I can find about it. It
has been discontinued for a while, from what I understand. I guess its
cost advantage over 8 bitters didn't persist.

That would be one of the functions of the timer chip, if that's what you
are getting at.
> If the company makes a new product, that's a new product.
If the new product can be made by slightly modifying the old product,
they're not going to start a new design from scratch. There is a whole
engineering discipline about dealing with lots of product variants in
the field, at least for large products like aircraft. No idea about how
it is done for coffee pots but it's a safe bet that they aren't idiots.
