Ha! That's actually how I feel all the time. Learning something new is hard. If I don't use it I start to forget it. I do have two degrees: Engineering and computer science. I always thoguht this was normal. Maybe I'm stupid and never realized it? Iwonder...

My bet is independently. Spanish also has the same expression and I bet lots of other languages do too.

The Spanish and English dual meaning both comes from latin, so the similarity in other languages with influence from latin does not provide any evidence in support of this idea developing independently (nor does it provide evidence against it).

Looking up the Chinese etymology seems to imply both the Latin and Chinese probably came to have the dual use for the same reason (agriculture leading to equating labour with resulting in fruit/produce), without any obvious direct connection.

Who knows... It does seem a quite logical step for new agricultural societies to make that connection.

Large crop yields = good thing. Seems like a reasonable connection.

He is is making the correct assumption that even if some people want peace others will be more than happy to kill you and rationalise that it was actually a good thing. So you are both right: the alternative is peace or war. I would definitely prepare for war though. To do otherwise is naive and gratuitously stupid.

Si vis pacem, para bellum may be a practical advice, but the outcome of it is an arms race. Which is a big problem, because that feedback loop ties up resources and manpower that could be better used elsewhere. So even if it is the most practical option now (since we don't have a single global government), we need to recognize how shitty it is and maybe figure out how to reduce its impact.

The pope outlawed slavery of the native population.

Reminds me about the article explaining how a couch textured with leopard skin got confused as a leopard by an AI algorithm. I assume something similar is happening here.

Call me stupid but I thought corn was native to the Americas. I guess something is getting lost in translation.

Also: https://en.wikipedia.org/wiki/Maize

"Corn" can refer to cereal crops in general.

'Corn' means the main cereal plant in a region.

Isn't the problem with California the farmers? Blamming the immigrants is an easy scapegoat. I remember seeing commercials trying to blame immigrants too. You drank their koolaid?

I can see the racial bias too.

I didn't read the part wher he mentioned hydrogenetad oil.

You do know that in situations like this you can always balance the scales? There are many legal, although maybe immoral ways to f*ck over a profesor like this. Nobody is immune.
