LN is not activated yet.
It's not a soft fork, so it doesn't activate. Your statement therefore doesn't make any sense
Lightning is already running, but still in a beta form. The UX is fairly clunky and there are potential bugs in the various implementations. It's not ready for mainstream use yet.
Even when LN is activated I don't know if it would solve things up.
The transaction capacity of Lightning is only really limited by it's BTC capacity & it's routing resolution. As long as the incentives work out, it could be so widely used that scaling will rival incumbent payment networks (Mastercard, Amex etc) and completely eclipse SWIFT. How much more capacity could Bitcoin need than that?
