I just looked up and realised that various companies had been using FTTC or VDSL2 in the past in HK which would solve the village fibre issue; even if VDSL2 only goes up to 100-200Mbs then it will still be more than ten times faster than ADSL 8Mbs but they wouldn't have to shove fibre into every house.
In fact, with all villages being so densely packed it would only require an upgrade to one exchange to get the service to each respective village (unless they're really remote).
I should stop dreaming, as PCCW are a monopoly with no real government oversight they can continue to do or not do in this case...anything.
