when llms become fluent in writing assembly the programs they can write will be orders of magnitude faster than even what most pro level programmers can write on same hardware.
i mean, its possible that compilers are so inefficient you can theoretically run same logic program on single pc faster than rest of the computers in world combined.
optimization may hide the hidden power in computation everyone is underestimating.
what if your personal computer is faster than the super computer in google data centers?
yes, you may be underestimating power of optimization, because you think compilers are efficient. what if they are not efficient at all.
do you think you need ryzen 9950x to render text on web page? in 2025 you probably need it. but same could be done faster on pentium 2. its simply that abstraction on abstraction has made doing simple things so much slower that basically all technological progress in rendering text on web page has diminished to zero gain. we still render text on web page same speed it was rendered in 1995 despite all the progress made on computer hardware.
c++ is not efficient language.
now you can try simple test in your favorite programming language:
how long does it take to loop through all values in a 64 bit integer? i bet it will take years unless you use assembly, which runs this program in 2 seconds.
