> there will be serious inflation in the next 20 years - I have no idea when, but bond yields will drop or become negative at some point.
These two statements are contradictory. Bond yields will skyrocket in the face of inflation. If you meant bond prices (which move inversely to yields) then you would be correct but your assertion, as presented, is false.
Also, please pick a 20-30 year timeframe in the last century where investment in bonds (for the entire period) would have underperformed (be destroyed, in your words) the S&P 500 for the same period.
