This is already not true - if I interpret blockchain.info's statistics right, so far, we had four blocks with more than 1 MB (these need to include Segwit transactions), three of them mined today:
- block
481947 (1,032119 MB)
- block
482152 (1,00003 MB)
- block
482187 (1,00003 MB)
- block
482191 (1,00001 MB)
So things are moving slowly, but they
are moving.
Maybe segwit is not yet fully active?
It is fully active. It is just broken. It doesn't do what they said it would do. They told everyone it was part of a scaling solution. Obviously that is incorrect.
Its not broken, its working as intended, perhaps you just don't understand it properly.
You are right, most people including me do not know how to use it.
Do you know how to use SegWit? According to
https://bitcointalk.org/index.php?topic=2128315.0 there is no user interface yet to use SegWit.
SegWit works, but it cannot be used yet.
