What could be the reason behind this? Asking as a noob Abstractions piled on top of abstractions. Something that might have been 5 function calls deep on either side with a carefully crafted packet in the middle is now 100s on each side. We have a culture that prizes programmer happiness above all and this means everyone thinks "this is a mess, I'll put my own layer on top to make it nice, then work above that layer". Repeat 100 times and now you have processors literally 2000 times faster that struggle to even keep up with keypresses. But what noone wants to admit, is that it's messy because the problem domain is messy and sometimes you just have to live with the mess and get some real work done. The programmers of old understood this.
