Then there is no hope. The majority of humanity will die and be doomed to eternal torment.
PS: The analogy of free will sentient humans to angels is logically sound, no "incompatible properties" exist when it comes to choosing light over darkness, freedom from sin and delusion by intelligent Beings having free will.
Although angels are superior to humans in many ways, it is the implied premise of God reigning over the angels in human nature we are not inferior to them in IQ
5 For He has not put the world to come, of which we speak, in subjection to angels.
6 But one testified in a certain place, saying: "What is man that You are mindful of him, Or the son of man that You take care of him?
7 You have made him a little lower than the angels; You have crowned him with glory and honor, And set him over the works of Your hands.
8 You have put all things in subjection under his feet." For in that He put all in subjection under him, He left nothing that is not put under him. But now we do not yet see all things put under him.
9 But we see Jesus, who was made a little lower than the angels, for the suffering of death crowned with glory and honor, that He, by the grace of God, might taste death for everyone.
10 For it was fitting for Him, for whom are all things and by whom are all things, in bringing many sons to glory, to make the captain of their salvation perfect through sufferings.
11 For both He who sanctifies and those who are being sanctified are all of one, for which reason He is not ashamed to call them brethren,
(Heb. 2:5-11 NKJ)
Angels have technology that far surpasses us, but that is an "accident of history". If the fall never happened, and death never entered creation, both angels and men would be equals intellectually and both joyously working to expand the wonders and glories of New Jerusalem:
2 Then I, John, saw the holy city, New Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. (Rev. 21:2 NKJ)
