An engineer should also note that any L2 that behaves like a BFT of dozens of operators is fundamentally more reliable than a P2P network trying to do to money what ISPs did to internet packets, ignoring that isps don't need a balanced egress and ingress.
A Drivechain where miners hire and fire 50 something operators to act as a decentralised permissioned BFT, could have worked almost as well as Visa and MasterCard if not better.
But Bitcoin not only refusef to enable bip300/1 it refused any opcode that could possibly emulated the same effect...
If we ever get GSR it might be too late too.
