> things have changed now in a sense that handful of companies are large percentage of the stock market to the point where one has to question why invest in “s&p 500” vs “s&p 25-ish”

A small number of companies have always driven most stock-market gains. Betting on size isn't fundamentally a bad bet. But it is a bet against value and the historical tendency for small companies to be higher risk and higher reward.

you may be technically correct but today’s concentration in say top 10-15 companies is historic and by significant margin. I have been self-employed for a long time and somewhat “forced” into being “an investor” and starting in 2021-2022-ish I took my money out of all the “funds” … while I do not disagree that it is “a bet” - it is a calculated bet. things are different now even if historically you are right, no question
