Not an exact analog, but "real" wasabi is exceptionally difficult to grow because it needs a stream with moving water, and a specific set of nutrients in the soil near the stream, and it is tough to fertilize them because the water needs to be moving. And if you don't get the nutrients right, the roots are too small/craggy to use, because you have to cut off so much of the skin of the root, so it needs to be fat to use. So most wasabi paste you buy in the store is regular horseradish with some added color and flavor.

Also, in the animal kingdom, it is considered generally impossible to milk a pig, even though they do produce a significant amount of milk. You can buy cow milk, goat milk, even llama milk, but not pig milk. The basic reason is that mama pigs are very aggressive and large animals and nobody has been able to develop a process to consistently get them to cooperate enough.

I also work with machine learning and AI a lot. I second this so freakin' hard. It is a huge triumph that things like Google Document AI and Textract can look at an invoice and figure out that the line item text is associated with the amount invoiced. ChatGPT might appear it is 'smart' but it is literally just a statistical model predicting what the next word would be, given the previous words in the sentence. It doesn't actually have creativity or ambition.
