Exactly. While there are some engineering challenges to be solved nobody informed is seriously concerned with path finding. Also people could develop their own version of LN with everything listed there being "fixed". That's where the problem lies.
You bet - they dont seem concerned one bit with promoting an incomplete concept as a defined solution. Many of the changes being forced into Bitcoin *today* are supposed to be required to enable LN - but as you have stated above we are nowhere near knowing exactly how it is going to do what it does.
In telecoms we call what LN is trying to do "correlation" - i.e taking high frequency, low value traffic and generating lower volume, high value data streams instead. The methods proposed by Blockstream so far, while not impossible, are far from optimal and will prove an absolute bugger to deploy.
But why all the "we must do X now so that LN will work"?
Most people in this community have no skills or skills that are mostly useless and thus we just see them make hyperbolic complaints (out of boredom maybe?).
I'd contend that your comment is more a reflection of your own ignorance than the alleged ignorance of anyone taking the time to look into it and voice a concern.
