Reply to What if language IS the only model needed for intelligence? by wowimsupergay

language is a way to express ideas, ideas come from what we experience and think about, in order to experience things and to know that you as opposed to someone else or everything else is experiencing things, you need senses, visual, auditory, sensational etc.

LLMs maybe be able to replicate our thinking patterns by analysing our texts but, for them to be truly intelligent they need to be able to see as well and understand what we are referring to when we say "dog" or "animal"

Reply to comment by Eokokok in Heat Pumps could supply 20% of building heating by 2030. Supercritical CO2 heat pump sales in Japan have now reached a total of 8.5 million units. by DisasterousGiraffe

You have to realize that people have limited money. Of course the best way to go would have been to buy the house, insulate the roof, the walls, change all windows and the heating at the same time.

But we can't afford that. So we start with the point that saves us the most money, is mandated by the government and subsidized by 50%.

At this point, we have costs for heating of about 1500€ a year. Upgraded roof insulation could bring that down to 1000, but would cost approx. 30k so it would pay for itself in 60 years at current prices, at that time I am 97. Walls have a similar ROI, Windows are worse.

Well insulate the roof when we redo the tiles, we'll insulate the walls when we renew the paint,... And when we are done with that, we probably approach end of life of the heat pump anyway.

Oh, and by the way, energy efficiency class C(after renos) or D (before the renos) is nowhere near as bad as you claim it is.

Reply to ELI5: why does the US need the dollar to be the only primary form of currency for oil? by aresyves

If countries only buy oil in dollars they need to get dollar from somewhere. They need to sell something else and get paid in dollars.

This is and advantage if you have dollars.

Furthermore since the price of both dollars and oils goes up and down all the time, you don't wan to exchange your own currency or sell stuff for dollars at a bad time.

You wan to get dollars while they are cheap and use them later when you can buy oil with those dollars cheaply.

This requires you to keep a certain amount of dollars in reserve.

Dollars that you don't actually use to do anything with them but keep nonetheless available to you if you need it.

This all adds up to people need dollars much more than they would otherwise.

Supply and demand happens and since so many people have a demand for dollars you can add more supply without making it worth less.

It is all much more complicated than that, but it all adds up to a huge advantage for the US and the people in the US who have money.

The Dollar being used for oil transactions provides a degree of confidence and stability in the currency without being explicily tied to the value of a commodity.

This allows the US to engage in flexible monitary policy without running as much of a risk of severe inflation or deflatation, as even if the dollar loses some value, people will not be prone to quickly dump all of their dollars in favor of some other currency.
