Wow, thanks for the in depth reply! Probably will do as you suggested and just buy the most expensive one I can afford.
The reason I was a little scared of temperature issues is that my MacBook right now turns into a room heater as soon as I do something more complicated than using notes. To the point where it damaged the screen when I worked on an external display with the internal display closed. I’m very glad to hear that that doesn’t seem to be an issue anymore with apple silicone. It’ll be so nice to be able to use my laptop on my lap again!
People in western nations are largely responsible for climate change. Someone in Syria won’t be flying around the world and buying new clothes all the time. But they will be the ones hit the hardest by climate change, so they will likely either die or become refugees trying to come to the west.
Also, a lot of our western wealth is based on exploitation of those nations (through colonialism and later capitalism or wars). So if westerners don’t want people from poor countries to come to the west they should help those nations to recover from that exploitation.
Furthermore we need to do these things, because a bigger influx of desperate migrants will steer western politics even further to the right. That’s never a great thing and will lead to more inequality and possibly the collapse of our democratic systems.
Finally to your point about migrants being more criminal. That is largely a result of worse economic circumstances and outlooks. Improve their chances and watch the crime rate drop.
