-ck's response.. close eyes, put fingers in ears and just scream go with segwit.
(facepalm)

1. segwit is not as 'compatible' as promised
2. segwits activation event itself, is not about solving quadratics/malleability scaling or anything else. its about setting up the tier network
3. moving funds to segwit keys after activation has a POTENTIAL to affect quadratics/malleability scaling or anything else.
4. but malicious people will stick with native keypairs and continue to do quadratics/spamming to prevent good utility
5. segwit does not stop/disarm/solve native keypairs. thus not 'fix' issues.
6. segwit just disarms innocent people who volunteer to move funds across while letting the network continue doing the same as usual.
7. the 'expected' potential scaling boost of segwit is the same potential scaling of 7tx's on chain of 2009-2017. which still has no guarantee of actual achievability
