When, if at all, do we say the blessing on great Torah scholars? The custom seems to be not to say it.
There are different opinions if there is anyone alive nowadays that this bracha can be said on him. In Eretz Yisroel there were a number of gedolim, that said it when seeing Horav Chaim Kanievsky shlit”a, others however hold that we don’t say it at all nowadays. See Piskei Teshuvos 224-4 for the various opinions.
