This exactly, there will be a time that we run into the 1MB block limit. This needs to be fixed before the blockchain grinds to a halt (maxes out on TPS really) and transactions take forever to confirm.
this is exactly what will NOT happen. The chain will not grind to a halt. You have no evidence to back that claim up. It's just fearmongering/FUD /doom preaching
....The current network can support 4200 transactions per block (estimation) (assuming exactly 10 minutes per block) before hitting the 1MB block limit. After that transactions will start queuing up and you will have to start waiting for your transaction to confirm. Why would you want that to happen?
