Let's say that Ethereum 2.0 got cancelled or postponed once again how long do you think that a 6GB memory will last for ETH mining? I'm aiming at 6GB graphic cards can they last ETH mining specifically till 2024?
Yes, i posted it very often:

(not say ROI as all said here, goolge ROI to understand how to use it
