First of all, yeah it sucks. It's sad spending a lot of money on something and having it broken a few days later. So, I feel you.
Now about the rest of your post, boohoo! Give us a break! You DID beta test the product. You played the game, you lost. When you bought it, you knew it was the first of a kind. So you knew you would gonna be a beta tester. And in fact you did. Just because everything else is the same as the previous gen, it still has knew CPU tech. Maybe now Apple is rethinking stuff. Or maybe you just got a unit with flaws...
Ok, youtubers are pushing the machine at its limits and "selling" it like it's a beast capable of 32K rendering easy. Their fault on that. BUT... there's a reason why Apple launched two laptops at the same time, one called "Air" and the other called PRO. For two weeks I'm seeing people telling that there's no difference between the two except for the fan and the pricetag. But guess what: maybe, just MAYBE, one being called Air and the other being called Pro means that they are suited for different kind of workflow, right? Or maybe you just got a unit with flaws...
Again, I'm sorry your laptop got screwed.
