the battery often dies around the time most people would consider upgrading anyway

Most people I know would prefer to just use the same phone they're familiar with until its physically not possible. They don't want to learn new things. They dont care about the latest features. It's an appliance; a means to and end and nothing more.

Because in the software engineering world there is very little engineering involved.

I can count on one hand the number of times I've been given the time to do a planning period for something less than a "major" feature in the past few years. Oddly, the only time I was able to push good QA, testing, and development practices was at an engineering firm.

I've housed two sibling that were labeled as "mentally unstable"(raised by mentally abusive narcissists) and "lazy"(has narcolepsy), respectively. Both situations were pretty bad before they landed in our home, but everyone in their lives called us "angels" for taking them in.

Each of them lived with my family for two years. All my wife and I did was let them exist in their own space with no pressure to do anything (other than coexist in our house, but that's purely logistics).

Both of them have gone on to go to college and pursue their respective dreams. The elder of the two lives independently, and the younger just shipped off to college.

The broader point being that most people just need a support network and a stable place to live to start to thrive.

Granted, that's just anecdata on my part, but it seems to line up with moth metal health studies I've read when it comes to homelessness.

but norepinephrine is actually the common thread among all ADHD medications

Anecdata, but my ADHD (and depression!) didn't significantly improve until I was on both lisdexamfetamine and buproprion. Both drugs lift production of both neurotransmitters, but they "specialize" in dopamine and norepinephrine, respectively.

People who have been doing this their whole lives can probably aim with a precision of a Marine Corp Sniper but to us

I bought these sprayers for my house when people lost their minds hoarding toilet paper during the initial COVID lockdowns in the US. It only took a few days to start getting it right the first time, every time.

LLMs can reliably solve the problem of a blank-page.

This has been the biggest boost for me. The number of choices available when facing a blank page is staggering. Even a bad/wrong implementation helps collapse those possibilities into a countable few that take far less time to think about.

creat[e] a graph where each permutation is a vertex and every permutation is connected by an edge. Each edge has a weight associated with it; the weight is calculated by seeing how many characters can be added to the end of one permutation (dropping the same number of characters from the start) to result in the other permutation. [...] Any Hamiltonian path through the created graph is a superpermutation, and the problem of finding the path with the smallest weight becomes a form of the traveling salesman problem.

none of that is the same as spending time to figure out how to ensure that something breaks at the right time

Yes it is. At the absolute limit, balancing cost and reliability is this exact optimization exercise; we are talking about the exact same thing taken to different extremes. The difference between your ideal scenario and the practice outlined in the OP is the difference between 97% BOM efficiency and 99.99% BOM efficiency. At extreme scales, that gap can mean the difference between a company laying people off vs. surviving.

Side note - this same discipline is what ensures your widgets fail in a safe, controlled manner and not in a catastrophic way.

I feel like you're reading my message extremely uncharitably

I saw an naive take on how mechanical design for failure works in practice and wanted to educate. I mean no disrespect, it's just seemed like it might be an unknown unknown for you. Your comment had at least a few upvotes, so there are others out there who may also lack the same information.

To your charitability point, though, my first take on the OP above is probably the most charitable take. The least charitable scenario for the OP is that the company wants to make sure they have higher annually recurring revenue from replacing their widgets breaking down but need to _barely_ beat or match the other guys in a warranty. Reality is probably somewhere in between.

In mechanical design, you typically target an order of magnitude of stress cycling for product design. In a pump, everything stress cycles, so it all needs to be simulated. If this was a pump you were going to make ten million of, then suddenly every fractional 10th of a cent you save becomes the difference between, e.g., having another coworker or not. So to balance that with offering a reasonable warranty such that there's actually demand for this product makes sense.

Before anyone brings it up: sure, a lot of companies just pocket this savings or whatever, but a lot don't; you just don't hear about them because they're typically midsize companies that nobody complains about.
