Here's another: As long as the law of supply and demand defines the price of block bytes, we can never on-board billions or even millions of people on a layer-1 solution, unless we undermine another important property; being practical to verify the ledger.
Iirc last time we had this there were two directions for action:
1. get the community point their finger towards the services (wallets & exchanges) that were spamming the network
2. get bitcoin one step forward with SegWit
Imho telling that current situation is OK is not the best course of action.
Back in the day, people here were not only technically-minded, they could actually program fixes for these kind of things in whatever language it happened to be in.
So there was a lot of intellectual investment by the community into the problems that happens to be going on inside Bitcoin.
If we are to move anything forward then we need to revive that spirit. First (and not necessarily talking to anyone in particular), wise up on your Bitcoin skills if they need refreshing. Then, go to the new bitcoin-dev mailing list on Google Groups and start reading what other people are doing.
Just a few days ago there was confirmation that new BIP editors will be added, so it's not like Bitcoin's going to be stagnated anymore. But it needs innovators!
