V'Darashta V'Chakarta: A Bracha Upon Seeing A Brilliant... Am Ha'Aretz

The Shulchan Aruch (OC 224:6) paskens that when you see a "Chachmei Yisroel" you make a Bracha "SheChalak MiChochmosoi Lirei'av"; He gave a portion of His wisdom to those who fear him. When seeing a Chochom who is not Jewish you make the Bracha "SheNasan MiChochmosoi L'Basar V'Dam"; he gave from His wisdom to flesh and blood.
 
Rav Aharon Yehuda HaLevi Grossman was asked (V'Darashta V'Chakarta 3:27) what happens if you see a Jew who has reached the level of "Chochom" (this determination is not the scope of this article and is a disputable matter), but only in worldly matters and not in Torah, do you make the Bracha "SheNasan MiChochmosoi L'Basar V'Dam"?   On one hand, he is walking model of Hashem's wisdom, which deserves a bracha to Hashem.  On the other hand, maybe this bracha only applies to a non-Jew since the gemara specifically says if you see a wise man from the "Umos HaOlam".
 
Although he leaves this question unresolved, he writes that he heard (although he never saw this himself) that Rav Yitzchok Hutner wrote that if we were to see Albert Einstein, we would not make the bracha, since it is an embarrassment for a Jew to be wise in worldly matters but not in Torah knowledge.
