@sig,
Check out blockchain technology if you want to grok immutability. In a future time, all truth will be encoded on a blockchain. Then you won't have to reference the rarified space between my ears for your serving of hard truths.
Hmmm, block chain head. That _does_ have a nice ring to it!
Greenyer's committed to using it, I see, for posterity's sake.
Probably a good idea.
And while I agree that _some_ truth will be encoded on a blockchain, much error will be as well. Discernment remains essential. And certainly not _all_ truth, given our finiteness and limited capacity for expression, no matter how brilliant or wise our cumulative and collective insight.
