While alone this by no means makes index funds a bad investment the average life expectancy of an S&P company has shortened dramatically (the exact figures are easily google-able) which possibly presents a new type of risk they have never before faced.

If you think this isn’t temporary and maybe will continue I think it stands to reason that in the case of broad market indexes like the S&P the decisions of individuals involved in curating the index will become more influential. Which is somewhat antithetical to one of the hallmarks of an index fund; eliminating the need to pick well.
