I did try to temper these superlatives in the interview. Everyone who has been compared to Buffett (though I don’t know if they brought it up themselves or the interviewers did) has usually experienced a massive reversion to the mean or an outright collapse in the investment markets. I have, however, already experienced this preemptively in recent years. 
Buffett’s partnership yielded 26% per annum, if I remember correctly. Berkshire’s first decades—note: decades, even as the scale kept ballooning—were well over 20%. No one really compares to him. Except maybe Stanley Druckenmiller etc., if he continues active investing for another ~20 years.
