There are no clear consensus to Bitcoin scaling problem but whether BU or Segwit will not be implemented for now will not be a problem in Bitcoin cause this currency will still move forward.
The bitcoin network can still handle the volume of transactions in a daily basis with the drawback to pay high fees in order for your transactions to get confirmed faster.
I think this problem will remain for many years if the community continues to debate and argue for betteflr solutions.
If by "not a problem" you mean its ok for Bitcoin to possibly lose opportunities for investment, mainstream adoption, and continued clear dominance as the #1 crypto, then sure, its not a problem.
