in this example i mentioned, you'd actually have managed to write a software that can calculate it for, say, 1 to 105 atoms on a supercomputer. but you also notice, that really, 106 would take double the ram or double the cpu.  the trend then becomes clear: it's going to essentially take nearly infinite time or infinite improvements to the computer to do much or the entire problem here. on the other hand, that tiny quantum chip comes and both theoretically and practically does this specific problem with various test cases for 1 billion atoms and it easily looks like it can be scaled if you just make it bigger.  no, it won't really do a simple 1+2+115 or "everything" faster. but this problem, it does really amazingly much better. but it's also fucking hard to set up and keep usable for a few nanoseconds until you have an usable intermediate or final result - engineering wise. and adding more bits and getting them into the probably correct initial state to do the calculation to it still is essential. just hard. you even don't need it to work every time but just more than randomly because yea, you can do this 1 billion times and check the most common results and probably have the right answer still much faster and easier than the normal computer would. it's still hard.
