My only complaint with this article is that it seems to be implying kafka that linkedIn's problem couldn't have been solved with a bunch of off-the-shelf tools.
And what would that off-the-shelf software have been?

This isn’t true. You can grow - it’s just the seasons are different or offset. In the warmer climates you actually have a longer growing season than say New England. Your local extension office can explain.
For example, here is the UFIFAS which is very good

I think you're overstating his point.
While you can grow them in, lets say, Houston, they're not easy to grow. They get infections at the drop of a hat, and if you so much as turn around, some sort of insect will munch through them. They don't yield much fruit, and the fruits they do yield generally leave something to be desired in the flavor department.
This is his point. The plants don't have much energy to fend off infections or predators, and they don't have much less energy to put into their fruit.
If you put a tomato plant in a more suitable climate, the things are nearly weeds. You put them in a bucket, make sure they get enough water, and you a few months later you have sweet, juicy, flavorful fruit with basically zero effort.
While we've bred cultivars that can be grown in places like Houston or Florida, the plants don't particularly like it.

When I grow up, I realize that fairy tales are almost lies.It is difficult for princes and princesses to live happily ever after～
Tell me you've never read the original fairy tales without telling me that you've never read the original fairy tales.

The author's first example seems to undermine the thesis. Their Point class allows two separate locations to independently update the X and Y fields, leaving the object in an inconsistent state.
It seems to me that this is exactly the sort of thing that Rust is intended to prevent, and it makes complete sense to reject the code.

They gave the mice 15mg, which is about a low-medium dose for a human. But humans weigh about 2000 times what mice do, so the effects were observed at about 2k times a reasonable dose.
1) Those mice must have been completely out of it. 2) This probably isn’t helpful to humans unless given under sedation. Or maybe that extreme a dose is equivalent to sedation, I’m not sure anyone has taken 30 _grams_ of psilocybin to tell us?
The human equivalent dose for a 70 kilo person is around 85mg. See https://pmc.ncbi.nlm.nih.gov/articles/PMC4804402/

Across species dose adjustment is based on surface area rather than mass.
Mass is proportional to volume. Volume increases super-linearly with respect to area. Therefore area increases sub-linearly compared to volume. Therefore dose increases sub-linearly with respect to volume. Therefore does increases sub-linearly with respect to mass.
Fruits and vegetables from a few hundred years ago would be almost unrecognizable and unpalatable to modern consumers. The colorful, delicious, and durable fruits and vegetables of today are the result of lots of work and selective breeding.
Most fruits and vegetables in grocery stores taste pretty bland. They're bred more for appearance, shelf stability, regularity, and transport rather than taste.
There are legendary varieties that are lost to time. Occasionally we rediscover them, and we get to compare. Usually the modern industrial varieties are pale imitations.
> despite nobody really asking for them
What people say they want and what people choose to buy are very different things.
If you ask people "Do you want ____" in isolation, they'll always say "No" if they thing you're asking about has any negative connotation.
If you put two different products on the shelf next to each other that differ by that same thing and even advertise it prominently (e.g. one says "No artifical dyes or coloring") most people would probably choose the brighter one because, at time of purchase, their reveleaed preferences are actually different. Now add an extra $0.10 to the retail price for sourcing more expensive natural colorings and even more people will choose the artificial coloring version.
This pattern plays out prominently in all things food related. If you ask people "Do you wish the food supply was healthier?" everyone is going to tell you "Yes". Then when they're deciding where to go for lunch or what to order, they'll skip right past the healthy items and choose what tastes the best.
These hypothetical free-lunch questions are useless because consumers will always claim they don't want the thing they don't understand. If you ask people if they want their food to be "preservative free" they'll tell you yes, until they see their food going bad immediately and their options dry up. Ask if they want "anti caking agents" removed from food and they'll emphatically agree, until their shredded cheese is sticking together. Food science and popular opinion are two different worlds.
The problem historically was that when consumers were given detailed ingredient labels, they often decided to not purchase the products. Chemical and food manufacturers spent vast amounts of money to get ingredient labels watered down so that consumers wouldn't see the chemical names. In the 70s labels were much more detailed.
Labels like "natural flavors" exist to cover up what's actually in the food. "natural vanilla flavoring" sounds much nicer than "vanillin and acetovanillone extracted from waste sawdust".
Even in the 90s artificial dyes already had a bad reputation. The manufacturers must have considered removal and it's shocking to me that their analysis must have guided them to keep them in despite nobody really asking for them. I guess people love bright colors.
It's goes back even further. Artificial dyes already had bad reputations by the late 70s.
In the mid-late 70s labels on foods and cleaning products told you exactly what was in them. I remember because my father was an organic chemist by training, and he would look at most labels and explain what was in them, and why we weren't buying them. (My family ended up shopping for most of our groceries at organic food stores.)
It turns out that a lot of people didn't want those ingredients either, and it was impacting sales, so companies successfully lobbied to get the disclosure requirements watered down. These days labels in the US basically tell you nothing.
I studied organic chemistry in college, and there's little as disturbing to me as "natural flavors" or "natural colorings". You have no idea what the chemicals are, what they were extracted from, how they were extracted, and what compounds/processes were used in the extraction. It's a non-label that tells you nothing about what's actually in the food.
We should be entitled by law to know what we're consuming, so that we can actually make informed decisions, and industrial food manufacturers don't want us to know, and have spent vast sums of money to ensure that we can't easily find out.
