You hit the nail on the head.
In (A), we have no proof that 'these systems have met the original expectations of computer specialists'.
Perhaps the closest match in the passage that we have for 'original expectations' is line 10, but it says that these systems have 'fallen short of optimistic early predictions'.
To prove (E), we could use 33-37 and 54-57. The fact that we need to exceed the 'capabilities of the present or the foreseeable future' and to develop a system that moves us past an 'apparently intractable problem' is a good enough match for 'we need a breakthrough'.
A couple quick thoughts:
1. When the question stem says "most likely agree", treat it like "what is inferred/implied/suggested" ... i.e., figure out what's wrong with 4 answers, and find a line reference or two to convince you of the correct answer.
2. LSAT loves to create trap answers that are 1/2 right, 1/2 wrong. If your nature is to read answer choices looking for what works, you're liable to be fished in by the 1/2 right portion. Instead, train your brain to read answer choices looking for what's wrong ... here, your correct analysis that we never established these systems met anyone's original expectations would have forced you to eliminate A.
