... Give me back my caps!

This guy is entitled to use the word "plant" as he will, but it doesn't agree with modern systematics. For example he calls "kelp" a plant, but it is taxonomically closer to the parasite that causes malaria than it is to land plants.

"Macroalgae" is a multi-phyletic category, including eukaryotes of the Archaeplastida group that includes red algae and green algae and the land plants that evolved from green algae, and of the super-group Chromalveolata that includes red tides, brown algae (such as kelp or Plasmodium). Green algae and land plants are grouped together under the kingdom "Plantae" in modern taxonomies.

So "seaweed" as a category includes organisms which are (cladistically speaking) closely related to land plants (green algae like sea grapes or sea lettuce), middling-related (red algae like nori or carageenan) and not very closely related at all (brown algae like kombu/kelp). Of course all organisms are presumably related to some degree.

The seaweed in question is a kind of dulse, a red algae. It's more closely related to land plants than a brown algae like kelp would be, but less related than sea lettuce. Red algae are specifically not included in the Kingdom Plantae. However, layman are free to call whatever they want a plant, even if it's in fact something else entirely, the way they call any small arthropod a "bug", even through true bugs are one of the 75,000 species in the order Hemiptera (out of over a million insect species).

Technically it's not a plant. Its a macroalgae and thus belongs to an entirely distinct taxonomic kingdom from plants and animals. Of course halakhically it probably counts as a plant because Jewish law isn't based on modern scientific concepts.

Many years ago some of my wife's friends inhabited a kosher apartment near her engineering school that had been passed down through generations of orthodox students. A dispute arose over whether a particular bowl was glass or pottery. Finally they called in their buddy the material science major for a scientific ruling. "It's neither," he said. "It's ceramic." Which was technically accurate, but irrelevant to the question of whether it could be kashered.

Would need a side of Coke syrup to dip it in.

Just as good. Sell it in a powdered or grained form and subsitute it for salt in recipes or as seasoning. Could add a lot more nutritional value.

Why "of course"? If automatic-crash-avoidance technology can make it so that even (semi)manually-driven cars can't get into accidents, then there would be no safety benefit to outlawing (semi)manually-driven cars.

I can imagine a law requiring manually-driven cars to have crash-avoidance technology installed, though.

So should people with peanut allergies avoid Soylent Green produced in facilities located near mental institutions?

But when you add bacon they taste awesome. Bacon makes everyhting better.

Really, that's your logic? "X has never happened to me personally, therefore it must never happen in the UK"?

That goal might be a technically sound one, but I don't think it's politically viable. Telling people they are not allowed to drive their car anymore is likely to be even less popular than telling Americans they can't own a gun anymore.

A more attainable way to improve safety would be to allow people to continue to drive if they want to, but to add intelligent accident-avoidance software to the automobile so that when the person is driving, if the car notices he is about to cause a crash, it can step in and take the necessary actions to avoid or minimize the crash. In this case, if the car noticed that the driver wasn't braking sufficiently to avoid rear-ending the car in front, it could start applying the brakes for him. This approach is not only possible, but is already implemented in some cars.

People like this guy are why we cannot have nice things.

However, this thing could have some potential in the development of an extreme form of skeet shooting....

Perhaps that is actually a battery pack? I'd imagine something like this would need a lot of power if you want to go very far with it (and not risk collapsing in the middle of the street somewhere)

Originally Java was intended to fill all of the custom-client-side-logic use cases that JavaScript (and to a steadily shrinking extent) Flash do now. But it didn't do a very good job of that, and instead found its calling on the server side.
