How valuable is BRK being in top 10 holdings for SPY, VTI, VOO without being a “tech” stock?

I find it fascinating that Berkshire is only of the only non pure tech stock in the top 10 of these above.

With the amount of passive investing with 401k, 457bs, etc BRK has that benefit plus the history of the great company. I wonder just how valuable that is?

Plus the amount of cash and cash flow that BRK has makes me think it is a solid buy, especially in this market environment.
