The main issue is that lag is too general a term. Back in the old days, it meant network latency (the time needed for a message or a transferred file to be received by the receiver and the acknowledgement of the receipt to be received by the sender, known as the ACK/ACK handshake that suppresses the retransmission of packets). This can have multiple causes and is the final common pathway for a number of pathological conditions (no, not biological in this case of usage). To fix lag, a process similar to medical differential diagnosis is applied. Thus, when complaining of lag, people need to have ping data (tracert or similar program results) and a snapshot of the state of the backbone (internetpulse). IMO without that, people are talking past each other.

Indeed, in a world and life full of change, the only constant is human nature (A is A, after all :P).
We old vets need to keep in mind those who come after us.
