And that's part of what I mean: If you go to an architect, or a builder, and say "Build me a small bungalow" they will respond with questions: "Where?", "How many bedrooms?", "How many square feet / meters?", "What kind of roof?", "What kind of bricks?", and so on, and so on - because they are used to getting the details tied down in contract form so everyone knows exactly what they are expecting to get.
But we don't! We take "Build me a small bungalow" as complete, and definitive - and build what be think the customer might want: a one room bungalow with 8 kitchens and no bathroom on the side of a cliff. (And many will copy the roof from SO despite it being designed for a small lorry, the kitchens from QA where they used to produce McVomits burgers, and the front door from a web site they found that deal with rabbit hutches.)
I take care to tie down the deliverables - and generally stage payments based on their delivery - to avoid the "I wanted it to be twenty stories high!" bit.

Honestly - please don't say "WE"
I force people to give me what real 'what is it you want' - which prevents most of your problems. If they don't know - how should I know? It's there job to know what needs to be done and mine only to implement it.
This doesn't always win friends - the lazy ones and the clueless ones - wanting you (me) to do their job for them so they'll look good (or blame me if they don't) - keep getting sent away until they come up with something. I don't give them a blank check, there, either - as I have a site with roughly 500 users to consider and don't want one user's stuff to screw up the others.
Interestingly - it all works out. Using a line from a car manufacturer (or someone) "the quality goes in before the name goes on" - an the non-dullard senior management learned to appreciate a sincere effort to do it right the first time.

This is only partially true, as it depends on what you are designing SW for.
You have legal requirements in finance, in pharma, etc... We (in the automotive business) have a lot of norms[^], legal requirements, design rules[^] that we have to fullifll, and we are personaly liable in case of quality issue that leads to damages or injuries. Recent past gives many examples[^].

Yes, and generally speaking the software for those industries "just works" as a result - because everybody is constrained by the rules, developer and client alike.

When programming critical systems, we still use the "house" model. OTOH, software has become much cheaper because we (or our clients) are willing to accept a less rigorous model for most development.
Both models have their place.

Simple question: If you can build a circuit with discrete logic or simply program a cheap microcontroller and be done with it, what would you do?
Discrete logic costs next to nothing, but can very quickly hog up expensive space on your circuit board and complicate the board's layout, including problems with noise on the signals.
The microcontroller often comes in the same price category as the discrete logic chips it is supposed to replace. It's a single chip that has to be programmed to perform the function you want to have it for. It may solve the problem more elegantly than some bare bones logic could. Then again, a microcontroller with internal ROM and RAM and often diverse I/O ports seems a little wasteful for such a trivial job.
For example, I could build my interrupt control logic with discrete ICs or with a single microcontroller. The discrete logic would be simple. Interrupts that were not serviced by the time the signal becomes inactive are lost. There would be no masking and the priorities would be fixed.
The microcontroller could easily do such things, like buffering and holding interrupts until they have been acknowledged and serviced, masking interrupts or assigning different priorities.
Which way would you prefer? An 'object oriented' microcontroller where I just look at the interface and don't care how it does its job internally? Or better the minimalistic approach with discrete logic where everything is 'global'? Still, preparing a tiny computer on a chip for such a simple job seems extremely wasteful...

Definitely a microcontroller... The only downside of it can be the cost, but event there is no big difference... And of course there is the possibility of reprogramming the microcontroller with better code or even for an enterley different purpose...

Depends on the speed required: uControllers get more expensive at a faster rate as speeds rise that discrete logic does.
But generetrally, I'd go the programmable route, as it's a lot easier to add features or even make the main software easier and more efficient.
I had one board with three PIC devices and a Z180: one PIC for the head control (to offload the actual serial data timing), one to interface with the LCD (after we found that the Z180 was far, far too quick for the display to cope), and one to auto-range the PSU and provide a self destruct if the software was tampered with.

I agree with OG, uControllers are easy to modify if requirements change and may have wasted functionality but at the prices WTH! Also better to have the extra functionality and not need it than to not have it and need it, should requirements change.

It's like writing software -- implement a reasonable level of abstraction to plan for future requirements. So, microcontroller.
