Lightning Network ⚡ really proved its usefulness during high fee environment.  I tested and both custodial solutions like Primal, WoS and self-custody like Phoenix worked smoothly.

Obviously it was not a good time to open or close channels.

High fees provide the incentive to continue to innovate and scale. LN ⚡ can probably take us to the next billion users, but beyond that we are going to need even more scaling solutions.

For 8 billion people to use Bitcoin we are going to need a LOT more.
