I agree, but it does not REQUIRE the gifts persist until the coming of Christ. That premise is not necessary to Paul's statement.1Co 13:8 Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.
1Co 13:9 For we know in part, and we prophesy in part.
1Co 13:10 But when that which is perfect is come, then that which is in part shall be done away.
The meaning of vs 8 is found in vs 10 as when Christ returns all these things will vanish away except for love as love is eternal. We can certainly see that Christ has not returned yet so all those things listed in vs 8 will continue to be done in part as no one has knowledge in the full until He returns then all things will be revealed to us in full.
For example:
If I promised ice cream cones will pass away when the ice cream factory is built, does not mean the ice cream cone in your hand will not melt and cease.
I only promised ice cream won't be sold in cones once the ice cream factory is built.
