My thoughts exactly. Knowledge transfer in manufacturing / industrial environments is something that I'm working on. - Language models / NLP applications for processing large amount of technical text data (SOP, documentation, technical data, machine text logs, voice to text, video data processing for speeding up corrective action, training, onboarding and highlighting areas of improvement / bottlenecks), digitising d…

I'm a partner in a factory and I believe this is an incredibly important area, and the requirements are fairly different than normal "just put it on Confluence" workplaces, in a way that most tech people don't understand and usually completely miss the mark when they're doing product dev.

- Your team is out on the floor. Their hands have grease on them. Using tablets sounds great until you're trying to use it with a glove on it, or your hands are dirty, and it's hard to get grease off tablets. But they need the info out on the floor. Also, it can be noisy on the floor.

- The team tends to be very visual. They don't like tapping on computers a lot. Literacy ranges from pretty good to kinda OK. Sometimes they refuse to get (or wear) reading glasses for whatever personal reason.

- They're working on proprietary hardware, but technicians with the right knowledge are not nearby to come in and look at it. You really need to be able to see the issues visually. Sometimes even hear them. AR might be interesting here. (I spend $10k to fly a tech out for a few days to look at a machine. The bigger issue is that I lose $10k a day from one machine being down, and a tech might not be available to fly out for a week.)

- Predictive maintenance. The fancy sensors and whatnot mostly don't work. Tech people try it in a clean, quiet office and it works, and they can raise money on it from clueless VCs, so money keeps getting set on fire with smart AI machine learning magic motor sensor companies.

- Preventative maintenance. How to schedule, how to verify it was done, how to check whether it revealed an issue that needs a follow-up. Getting people to do it, and verify it was done, can be a challenge, but there are huge returns to preventative maintenance (for example: checking gearbox oil levels, verifying lubrication line function, checking valve temperatures.)

- Diagnosing machine problems. Using prior problem documentation helps team members see most likely issues. But many of these people don't really want to sort through a database of prior similar issues because they "know" what the problem is. How do you provide this information to them in a way that feels more approachable to them?

I could go on forever. Manufacturing is an interesting environment because downtime is usually hundreds to tens of thousands of dollars of hard cost per hour, depending on the operation, and they will spend quite a bit of money to stop it from going down, but culturally there's a vast gulf between the white collar SF tech bros and what actually happens in manufacturing plants, so innovation tends to be more limited.

Educational games. Hear me out. The way we teach us basically how we did it 500 years ago. This is stupid, boring and not scalable. We dont have enough teachers, attention span is short, education is costly. So we need something that scales, is fun and involves all types of media plus gamifies education. Think Skyrim or GTA meets MS Encarta

I don't believe at all in gamification in education. The kick that inspires new scientists and engineers comes from the gratification of learning or figuring out something as nothing feels better than figuring out how/why something is happening and how to push it to it's edge cases. Even chasing grades is a perverse incentive IMHO.

Think of it instead as designing tools that make learning fun, and enables that gratifying feeling you described. Lego, for example, has probably created generations of people with incredibly high levels of visual-spatial intuition who've all been inspired to go on to become designers and engineers of all kinds.

It doesn't have to occur within the walls of a school for something to be considered education.

Titan's of CNC and Haas both have great youtube channels addressing training because of exactly this.

>Titan's of CNC and Haas both have great youtube channels addressing training because of exactly this. I would love to get into aerospace manufacturing. Any chance a code monkey can make the switch? What is the entry level pathway like?

Sort of related but I, a 28 year old tech guy, am going back to school part-time to get a BEng so I can get into more aerospace-heavy roles. It'll take 6 years but I'm currently happy with my work so am not in a rush. Currently I work in networking/search for a defense startup so it's tangentially related.

Not tech but I think millenials, gen Z, and younger have lost the know-how to make a dollar independently of mega corps. I never see kids going door to door mowing lawns anymore, for example.

Non-tech DIY in general is becoming lost. There is so much knowledge available on YouTube but so many of my younger friends just pay people $hundreds to do very simple, quick things. I’m not talking about transmission replacement, but ridiculously simple things like fixing a leaking toilet and changing motor oil.

Re. Changing motor oil example: I gave up doing this when my cars started having non-standard nuts on the oil sump. I had to pay the garage to fit a _headlight_ recently because the bulb was practically inaccessible without either specialist tools or 3 elbows :(

There are shockingly few people maintaining the video encoding packages that most people rely on.

https://xkcd.com/2347/ makes me think the same is true of image software as well.

I'm pretty sure there's a timezone database that's maintained by two guys and literally everything depends on it to get timezones right.

When I was at Microsoft ~10 years ago there was a single guy who truly understood how tables in Word worked. I'm sure they've fixed it by now but back then if you wanted to touch the tables code in Word you had to talk to the tables guy to make sure you wouldn't break everything.

If I remember correctly there's a lot of low level networking code that's basically in this state. I think ntp is maintained by a single person. Curl was written by a single person, not sure who maintains it.

Tons of stuff in the geospatial world is owned and maintained by surprisingly few people like proj and gdal. I'm almost certain I saw something about all GPS code in the world relying on a package maintained by a single person.

PHDs are never going to be learning through games but I think at lower levels of education there's a ton of room to inspire a desire to learn something more deeply through games.

I agree that games intended to teach academic subjects are very hard to get right. Interestingly, when you take the arrow in the other direction, ordinary video games have sometimes been the arena of some very advanced "doing science", e.g.:

"Speedrunning as a gateway to scientific endeavours" https://www.youtube.com/watch?v=w8_1lQ2KH50

"The Complete History of the Super Mario 64 A Button Challenge" https://www.youtube.com/playlist?list=PL94lfiY18_CgWGQzweD_a...

I TA'ed at a tech camp a while back, and there was a 12 year old from Mexico city that had astonishingly good English. I asked him how he was so good at it and he just answered "Skyrim". So yeah, kids soak up a lot of info through games.

Traditional draftsmanship (not really tech is it?), as in with a pen/pencil on a draftsman table, has completely disappeared. My father is a (relatively) recently retired Architect, he ran a small but specialist firm of about 20 people. By the time he retired about 5 years ago there was no one in the office that had ever been trained in traditional draftsmanship, only himself. It’s a lost art. There are now almost tw…

Do you want to bring this back? CAD is a productivity multiplier. It's like composing a document in MS Word vs hand writing it.

Sure, I don't have an objection on that. In fact, anything up until college is actually distilled and idealised version of the ideas about how nature works. That's why people solve math, physics and other problems recreationally.

However I don't want to call it gamification because those are not designed in a game format in order to make you do something that you normally wouldn't want to do. Those are simplification or analogies to bring ideas within the grasp of the student so they can reach it with their current toolset but without mischaracterising it. So when a student calculates the trajectory of a ball in ideal condition, this is still a calculation of a balls trajectory and not something else.
