It's not just gen 4 that used a different translation for that line though.
RBY, GSC and their remakes use "Technology is incredible". RSE give it as "the power of science is staggering" , but the Japanese line in RSE IS different, so that's excused. DPP gives it as "Technology just blows me away". Black/White and Black 2/White 2 give it as "The power of science is amazing" (the fact that it stays the same between those and that and some odd system messages like telling you to enter "the name" if you leave your name blank and hit end suggest the translation made a point of consistency/reuse). XY give it as just "Science is amazing".
