if blocksize gets an issue it will be solved in 24h
its not a big deal, more a question of details
ideialy there wouldnt be this "blocksize" issue in the first place
but there is
so how do we deal with it
dealing with it by ignoring it until it actually start to mess shit up and then saying " that's fine! bitcoin was meant to be slow and costly, using the holly ledger is a privilege! " is wrong.
on ther other hand gavins proposal is equally ridiculous to the other extream.
i'm confident devs will implement a happy middle ground
blocksize is not ignored, i think now everybody is aware there is a blocksize.. have you check tx/s ?! only 7!!

anyway, whether blocksize being an 'issue' to deal with (now?) is on the other hand far from being justified, quantified.
however, im confident active (and everybody is free to join, if technically talented - and not so much of a reddit guru otoh would be a plus) core devs are researching it, analysing data, and studying effective 'scalability' solutions to be tested and implemented in due time and hopefully without tearing apart the fundamental properties that makes bitcoin special (secure&trustless&permissionless).
now if only the chief-scientist - whatever this means - and his google acolyte could fork off, like definitely, so grown ups could focus on making bitcoin stronger, not fancier.
