Yeah what matters in the end is % profits on money invested.

it's a bad idea to invest in companies whose business model you don't understand / have deep knowledge about.

It's hard for Buffet to invest in highly scalable tech/saas companies but it opens doors for younger investors that have a deeper familiarities with those deep pocket business models

Otherwise the market wouldn't evolve, what was true 50 years ago would still be true, market evolve not only by changing companies but also the way of thinking. This leads to longstanding companies losing ground and finally closing/selling out/ bankruptcy.

It would be boring if every old knowledgeable people were holding up to date knowledge, they can have lot of it ***but*** it's old/outdated knowledge.
