I guess I understood the gist of the flaw and what I would be looking for, but I struggled with the wording of AC B and also the usage of only in the conclusion "only those who appreciate these advances are computer scientists." Does it matter if some computer scientists may not appreciate the advances in technology if the pool of those who can appreciate these advances only exists within computer scientists? I thought it would only matter if all computer scientists happened to not appreciate these advances. Or is it the idea that some could mean all that is confusing me? meow
