the thing about scaling is that SegWit this increase the capacity it is just that not that many are using SegWit transactions so the effects were not palpable. if you check the block sizes we already had bigger than 1 MB blocks. i think the record was 1.7 MB so far.
the way i see it, LN is not supposed to be considered a scaling solution, at least not directly. it should be more of an indirect solution for scaling. LN removes the load of the transactions on chain so there are less "traffic". for example if you want to make deposits in your exchange account, your gambling account,... over and over, you choose LN and go off chain. that way a lot of transactions will get out and reduce the pressure on network.
with that said bitcoin does not need scaling right away. if bitcoin continued like normal without BCH difficulty manipulation and all the spam attacks against bitcoin, then fees would have never risen and mempool transactions would have never exceeded 10K, specially with SegWit now active. and it would have remain like this as SegWit is used more.
The failure to 2X or rather the 6 people saying NO, and they don't get to say no in general if people chose to run 2X, has rather caused the ossification of 1x to look more sure.
it wasn't just those 6 people saying no. it was all the NO2X crap that has been going on. SegWit2x would have led to a split or at least death of core and a crash of price nonetheless. even if temporarily.
However until BCH adopts segwit and so can run LN, it remains hobbled.
LN does not "need" SegWit!
So in short HODL
better say, HODL bitcoin, buy BCH, enjoy the pump, dump it before it is too late, buy bitcoin, HODL, enjoy the rally and come back of money+profit to bitcoin.
