The future is obviously knowable to some extent. Astronomy has a pretty good record. Meteorology less so. But my question cuts to the central issue of whether ID can be a science.
It seems that the assertion that life forms are designed implies that their properties are known in advance of "manufacture". Not a big job for God, perhaps, but a tall order for anyone else.
A lesser issue, and perhaps more ameneable to research, is whether allele changes have predictable consequenses. There are, of course at least levels of consequense. The first would be structural. Can the resulting organism survive. The second consequence would be ecological. How does the change affect the organism's reproductive success in a world teeming with competitors and preditors. Can this be predicted, even in principle?
This is the problem addressed by natural selection. Darwin's answer was variation, overproduction and selection: rinse, repeat.

But if the designer is a cosmic ancestor with vision/mind of an extra temporal dimension - and especially considering God the Creator outside of space/time - then the objection of unpredictability fails because the future is known for every design or design change.
If evidenced, your objection would preclude corporeal entities with four dimensional vision/minds moving on worldlines within the hypercube of space/time from being the "designer" in intelligent design theory.
That's a useful definition which I assert would narrow the field for possible designers to either outside the hypercube (God) or as cosmic ancestry (aliens, collective consciousness) with extra temporal dimension vision/mind.
