Hey, I want to take a break from the normal HN flow to wish everybody a happy Tuesday. Take a moment to appreciate the people around you. It's easy for life to speed by.

Anyway. I better quiet down. I'm sure the robotic bricklayers will be here to take our jobs soon enough. No need to rush it.

(Well actually, laying bricks is one of those fiendishly complicated problems at scale...)

The great contempt that computer people have for the skills that every human brings to the jobs that the do is always on display here. We haven't automated driving; we haven't automated picking tomatoes; we haven't automated bricklaying; we can't automate cooking a fucking hamburger. But they are completely convinced that it's just around the corner, because they are full of contempt for the skill and intelligence of…

I don't think this is it.

Computer people tend to work in office settings. The reason the old joke about threatening to replace people with shell scripts works is because a lot of office jobs can be replaced with shell scripts. This is because, rather than physically working in the real world, most office jobs entail manipulating symbols, which is easy for computers but hard for humans. (That's why we invented computers).

A lot of work in the real world entails some decision-making component that can be expressed in terms of symbol manipulation. This overlaps with the part that many people find difficult, because people are naturally good at physically manipulating the real world. So when we talk about automating driving or picking tomatoes or bricklaying, we are only accounting for the difficulty of automating the symbol-manipulation abstraction of that task.

(This is basically the conceit of "Manna", a science fiction story where a ton of jobs are "automated" by a computer that just gives a continuous stream of verbal instructions to a poorly paid human being.)

If you're measuring the skills of manual workers against the standard of how hard it is to build a robot that replaces them, they are surprisingly hard. The same is true for the skills of trained animals. Maybe we should start worrying about replacing human beings with robots after we've managed to figure out how to replace dogs with robots. Once we have enough bomb-sniffing robots, drug-sniffing robots, livestock guardian robots, police pursuit robots, search and rescue robots, and so forth, to the point where we don't need dogs, then maybe we can start to worry about the human jobs. (Or maybe not--dogs have a really good sense of smell that might be harder to replicate than some human capacities.)

I don't have contempt for the skills; I have great respect for the skills. I have contempt for the prices of things. If construction costs are cheaper than ever (are they really?) why can't I buy a box to live in without spending $300,000? Why is the permits process nationally broken? And despite being skilled, that doesn't mean they're informed: why do contractors not know what they're supposed to do? Why do the peo…

You can buy a box to live in for $50K. A place to put it, on the other hand....

I used to work in a family construction business and now I do machine learning contracting. When I compare the value you get for 300k worth of construction to what 300k of ML specialist time buys you, it's hard to agree with your comment. I understand the reasons, but generally I'm blown away by how cheap most labor intensive things are, compared to how much people will pay for software projects.

I don't agree with your comment. $50,000-$100,000 of well placed funds with the right software consultancy can generate a project that pulls in enough cash flow to pay for itself multiple times over in just the span of months.

Machine learning is not a high return investment on its own. It is only leveraged as a technical piece of an already cash flow healthy larger pie in most organizations.

The division of labor and supply of various workers makes most labor intensive tasks self-explanatory in cost.

$300,000 can buy you a property that takes years to double in value in comparison. They're completely different categories of capital utilization.

Please stop. The only ‘skill’ human beings bring to picking fruit or vegetables is their willingness to work for minimum wages because we as a society have failed to keep up with tech even as our population’s food needs exploded.

I think this is a rather harsh take. Most of the people working on automating it understand how hard it is and are striving through it. You need some of these irrational believers for progress!

Robots that can identify and pick up things in the environment haven't materially improved since the 60s. What has changed is how factories and warehouses are built, so that the 'environment' and the 'things' are strictly constrained to enable robotic arms to grab and move them. But let one thing get a little out of place, or worse, let a human get between an industrial robot and the thing it's trying to pick up and.. well. RIP.

I have done some workplace automation (building support tools to automate away stupid paperwork) and I've never ever felt contempt for the people I'm building tools for. These people do extremely intelligent work and make evaluations on complex scenarios - my tools only help them minimize the silly BS that slows them down, building layered tools on top of poorly designed assistive tools or breaking out greenfield solutions to help tackle problems that need to be done entirely manually.

I really disagree that almost anyone who has built tool assistance into someone's workflow will view their workflow as simple and view the employee with contempt - actually getting to know the BS they have to put up with on a daily basis actually deepens my appreciation for what they're doing. Sure I can cherry-pick examples that make folks look bad - employees today, even millennials, are for some reason allergic to learning keyboard shortcuts and will use right-click to paste. That's somewhat on them, but more on the company for not providing training time to teach better data entry habits.

If one of these highly skilled agricultural workers was given a robot that used scent to determine which fruit trees likely had ripe fruit that needed to be harvested - I'm sure they'd appreciate it for what it is, a tool that lets them concentrate on more important things. And, if we as a society are moving into a era where automation becomes so widespread that jobs are much fewer and far between 1) we'll waste a lot more time building freemium games or whatever BS labour sink society comes up with next and 2) we should realize that taxes need to go way up on the people still employed and UBI or other social services are needed to keep us functional as a society. Having too much productivity is such an easy problem to solve - you just don't do what America is doing and let it all coagulate into the pockets of a few hundred billionaires... and then everyone gets to live a good life.

I have absolutely no contempt for the skill. Why would I? But I do recognize that building costs are expensive and that building stuff could be faster and safer and thus think that automation would be good. Same goes for my job, really. Automation has so far been a net good for humanity and if we ever transition to a true post-scarcity society, it will be through automation.

Also, if you speak with people in ML/AI, they will not tell you it's around the corner. They know that physical stuff and robotics in general is hard.

Also, builders and the like often have a great amount of contempt towards any desk job - is that OK? Why?

> We haven't automated driving Yeah, we pretty much have... it just hasn't been widely adopted yet. https://www.youtube.com/watch?v=yjztvddhZmI And honestly, from a business perspective, most people really don't care about the skills ordinary people have. Look at the wine industry for example. Top shelf wine is hand-picked, for exactly the reasons you outline, and some people are willing to pay top dollar for that en…

We have not automated driving. Phoenix is step one but there are parts of the world that get weather other than sunshine. Yeah those cars are cool, but the roads in Phoenix are better than any other major city in the US, the weather is binary, sun or rain, the city is modern, and the stop lights communicate with audi (I think its audi) cars and you can see when it's going to turn green on the instrument display. Phoenix is the absolute ideal place for self-driving cars. Again, its a great achievement. They are doing great work, but I think it's a stretch to make the general statement that we've automated driving.
