The need for speed?
I can get up to 1 MByte/s download speeds with my plain old telephone line broadband quite a lot of the time, and certainly over 400 kByte/s almost all of the time. This is certainly more than enough for me for the occasional software downloads and iPlayer or radio streaming, so I don’t see any personal need to pay any more to have fibre broadband instead.
It’s good to know that faster speeds are available for those that need (or want?) it, and inevitably faster speeds will be needed for everyone if and when 4K video (etc) becomes more common, and obviously we would expect Openreach, etc, to gradually upgrade their network over time, but I genuinely don’t see the seemingly desperate rush for it (pun intended) that seems to be happening just now. I guess it’s better to upgrade the network before it actually becomes a bottleneck, I suppose.
