comment Why is serial data transmission faster than parallel?
The economics of Ethernet are different from buses like SATA — cables are very long and expensive to replace, so you focus on upgrading electronics at the end. Early Ethernet used 1 pair of wires but standardized on 4 pairs cables anticipating future use (at that era parallel was the obvious approach to faster transmission). This turned out to be hard, due to crosstalk, but since the cables are already there it was a shame not to use them. Eventually, it became possible to do crosstalk cancellation with very complicated DSP processing->D2A-> ...cable... ->A2D->DSP processing.

comment Why is serial data transmission faster than parallel?
The reciever doesn't have to wait for all lines to settle at the same time — fast parallel transmission nowdays involves measuring and then compensating for arrival delay on each wire separately. This even holds for short on-board links like CPU<->DRAM! This became possible by adopting some serial techniques like embedded clocks (e.g. 8b/10b coding) and/or training sequences.

comment What are the differences between fish and zsh?
The original developer is inactive but the unofficial fork(s) at github.com/benhoskings/fish/network have are picking up pace; the community is small but helpful.
