Agreed, and that’s the issue I have with the cash pile. They should be trying and failing quickly at a number of things, big things, including the small items you raised. Take a guy like Elon, give him a 500bn in cash and see what happens. The world would change in a big way.
Capital should be either sunk hugely into the R&D to change the world or should be returned to shareholders to better allocate it.
That said, These guys aren’t playing the game 1 qtr at a time. Not even a year at a time. They play the 100+ year game and likely they don’t see this money as “big”.
