There are no good short-term scaling solutions...this is a very hard problem that necessarily requires a lot of out-of-the-box thinking, something 2015 has seen a LOT of...and I'm optimistic about the ideas presented thus far.

At least SW *is* a scaling solution (albeit most of the important benefits are long term). The issue of fee events has nothing to do with scaling - it has to do with economics...specifically whether we should be subsidizing transactions, who should pay the bill for it, etc. My own personal opinion is that increasing validation costs works against adoption, not for it...even if it artificially keeps fees low - and we'll have to deal with a fee event sooner or later anyhow. You may disagree with my opinion, but please, let's stop confounding the economic issues with actual scaling.

A large part of your argument is that SW will take longer to deploy than a hard fork, but I completely disagree. Though I do not agree with some people claiming we can deploy SW significantly faster than a hard fork, once the code is ready (probably a six month affair) we can get it deployed very quickly. It's true the ecosystem may take some time to upgrade, but I see that as a feature, not a bug - we can build up some fee pressure with an immediate release valve available for people to use if they want to pay fewer fees.

That's taking a big risk.  "Build up some fee pressur e" is essentially risking a Fee Event if uptake is slower than planned, or traffic is greater than expected.

 

On the other hand, a hard fork, while simpler for the ecosystem to upgrade to, is a 1-2 year affair (after the code is shipped, so at least 1.5-2.5 from today if we all put off heads down and work). One thing that has concerned me greatly through this whole debate is how quickly people seem to think we can roll out a hard fork. Go look at the distribution of node versions on the network today and work backwards to get nearly every node upgraded... Even with a year between fork-version-release and fork-activation, we'd still kill a bunch of nodes and instead of reducing their security model, lead them to be outright robbed.

A hard fork will never achieve 100%  There are many credible folks and estimates who feel a May hard fork is reasonable and doable.

Further, hard forks restore the full trustless nature of the post-hard-fork nodes.  Soft forks continually erode that.  That's why SW should c ome via hard fork.  The end result is more secure - 100% validation of witness transactions.

If regular hard fork plans are proposed in public, many months in advance, there is plenty of time for the community to react.  Hard forks create a more predictable market and environment for Users, and a more secure network.

Further, even if you believe SW makes hard fork unnecessary, it is the responsible thing to code and communicate to users the plan for a Fee Event just in case SW uptake and extension block use does not match theoretical projections of SW proponents.

Finally, SW does not eliminate and is orthogonal to Short Term Problem #1 (orig. email - drift into ECE)
