Sure ok but to make that point you have to skip over all the other significant impediments to this plan.
You need to build, staff, and supply a local manufacturing plant for toothbrushes.
This is no small thing and not something that can be created overnight. It's not even as simple as "building" a factory... you need the supply chain, and most of the requisite supplies probably come from China - plastic to make the brush head, plastic to make the handles, machines to form the plastic, and technicians to maintain those machines. If you want to invent all these things locally and avoid the retaliatory tariffs from China, that's going to take decades.
During those decades consumers will be buying the tariffed Chinese toothbrushes wondering why the fuck everything from toothbrushes to shampoo to laundry powder to televisions costs twice as much as it does in any other country.
So my whole point is, there's a "threat" to Chinese producers but it's not very likely to materialise because the US will lose the political will to maintain the tariffs long before locally made products appear.
First time round you said "The aboriginal people were the first of Homo Sapiens to leave Africa." I merely responded that might be misleading.
it’s not disputable that Aboriginals were in the first wave of humanity to leave Africa.
No one is disputing that Aboriginals, along with every other race, descended from the first wave of humanity to leave Africa. That's what the article you linked from the smithsonian says. Well done.
You're conflating being the first to become Isolated (in Australia and New Guinea) with being the first to leave Africa.
But they did have to sail across the open ocean and did have to construct vessels that would allow them to do that.
Aboriginals migrated to Australia via land bridges and short sea crossings over the course of many thousands of years. If you want to call a hunter in a dug out canoe a technological achievement then you're welcome to.
they lived with them for 17,000 years.
This claim is derived from the existence of a single fossil. As you're no doubt aware, this is a subject of hot debate. Wikipedia says:
the main mechanism for extinction was human burning of a landscape that was then much less fire-adapted; oxygen and carbon isotopes of teeth indicate sudden, drastic, non-climate-related changes in vegetation and in the diet of surviving marsupial species. However, early Aboriginal peoples appear to have rapidly eliminated the megafauna of Tasmania about 41,000 years ago (following formation of a land bridge to Australia about 43,000 years ago as Ice Age sea levels declined) without using fire to modify the environment there, implying that at least in this case hunting was the most important factor. It has also been suggested that the vegetational changes that occurred on the mainland were a consequence, rather than a cause, of the elimination of the megafauna.
Yeah. "Both Names" for other countries is a bit lame but better than just Gulf of America everywhere.
The Denali / McKinley thing is pretty awful though. I hadn't realised Trump had changed that too.
