1 Corinthians 13:10 - has that which is perfect come?

When did that which is perfect come? Did it come or is it yet to come?
vs 12: - we see in a mirror dimly, but then face to face. Now i know in part, but then I shall know just as i also am known.

If that which is perfect is the 'canonisation of the scriptures' then how can Paul know, if he had already passed away before it occurred. Also Paul says 'he sees in a mirror dimly'. The mirror here is the 'word of God'. How can Paul see in a mirror dimly when the mirror wasnt formed till the books were canonised?

1 Jn 3:2 - beloved, now we are the children of God; and it has not yet been revealed what we shall be, but we know that when he is revealed, we shall be like Him, for we shall see Him as He is.
Tells us that by the word, we know we are going to be like Christ. But when we see Him at his second coming, we shall be like Him. So when that which is perfect has come (the second coming of Christ), we will have no more need for any spiritual gifts. We shall know just as we are known.
