The vast majority of time spent building software has little to do with optimization. Sky-high abstracted brain rot languages are useful precisely because usually you don’t need to worry about the type of details that you would if you were optimizing performance
And then if you are optimizing for performance, you can make an incredible amount of progress just fixing the crappy Java etc code before you need to drop down a layer of abstraction
Even hedge funds, which make money executing trades fractions of milliseconds quicker than others, use higher level languages and fix performance issues within those languages if needed
