<p>Really neat idea, I think it is one of the best ways to exploit the combined building and explaining capabilities of LLMs.
I am currently building an app/game to explain friends and family concepts around wealth management and wealth building. Games are a great way to hide complexity while still including it in the « guide » you are making.</p>

<p>I’ll add that you still need the will and the care to drive it towards an useful product. AI still not magically generate useful products if you don’t ask it to do it and prune the results until it approaches what you desired to create.</p>

<p>Nice article, interesting to keep an open mind.
On "No. 0002. Preserving problems", it can happen to people too, no need for a complex system at the size of a company. I have often noticed recognized experts keeping the root of the problem unsolved because it was justifying their position. I may even have been subject of this curse. As an expert, you may know the root cause but have no incentive to solve it and it can be harder to mobilize ressources to solve the root cause than to keep solving the superficial issue. It is management or outside help role to identify and push for solving problems at their root, but it takes time and dedication because of expertise. As most of the time, incentives explain nearly everything.</p>

<p>I have an industrial engineer education. My master’s degree was specifically a collection of small projects to demystify (and have the keys understand deeply) all kind of manufacturing processes and the designing that goes with it : machining, soldering, smelting, forging, electrical circuitry.<p>I ended up working in IT for a large company because of opportunity. Both in terms of interesting projects and pay. All my fellow classmates that went into industry seem to be stuck in heavy internal processes, or working like hell to finish projects that barely recoup their costs. Those who went into hardware entrepreneurship struggle to find clients and investors. The only sector that still seems sexy is the very high end for B2B and luxury.<p>My analysis is that scale cannot be reached by non Chinese companies except for very specific and high end products (that have a smaller scale by design). Therefore it is impossible to compete on the price/quality ratio of large scale products. And I end up thinking that tariffs could be the solution.<p>I am based in Europe by the way</p>

<p>Plus, back of the napkin cost shows it is not that expensive. 
30$ (or 20€) times 52 weeks : 1560$ (1040€)
Not cheap but less than 5% of a minimum yearly salary of 32k$. [1]
Same in most occidental europe. [2]
And not everyone reads a book a week (if only so…)<p>[1] : <a href="https://www.bls.gov/cew/publications/employment-and-wages-annual-averages/current/" rel="nofollow">https://www.bls.gov/cew/publications/employment-and-wages-an...</a>

<p>Related indirectly : Turkish airlines hub (Istanbul airport) is a scam. Everything there costs at least twice the price it should. Especially food which is basically what everyone does during layover. Think 30€ for a burger or a kebab.<p>« Brand new » is not an argument by itself.
Business is a must, or at least booking a lounge.</p>

<p>Setting for command is different from actual temp. Plus, humidity is rarely accounted for. A good AC that lowers humidity from 90%+ to 30% and this 30°C home becomes quite comfortable.</p>

<p>For exactly the same reason : space is scarce but power even more. Power can also become unavailable in a degraded situation much often than on land. Therefore, it is a better design choice to have a chest freezer.<p>In a city appartement where floor space is scarce, convenience is a key feature and power costs barely nothing, it is a less obvious choice.</p>

<p>Great project and build. I wonder if using a small fan would not help energy transmission, which is eventually the goal of cooking. It may also make the oven work like it’s at higher température while not consuming much energy. It would discharge energy from the walls faster using convection in addition to radiation.<p>Plus, you can experiment with tray materials depending on what you want to cook.<p>Suggestions inspired by my experience with convection/classic oven and copper pizza plates<p><a href="https://www.italiancookshop.com/products/hammered-copper-round-pizza-pan-tray-31cm?utm_source=chatgpt.com" rel="nofollow">https://www.italiancookshop.com/products/hammered-copper-rou...</a></p>

<p>That’s powerful. Most of the differences I can see between AI generated output and human output comes from the « broad but specific » context of the task. I mean company culture, organization rules and politics, larger team focus and way of working.

The « glyph » search part of the site is maybe the best asset to start with a database of possible matches.</p>
