'foreseeably-advanced' originates from the combination of 'foreseeably' and 'advanced', where 'foreseeably' is derived from 'foresee', meaning 'to see beforehand', and 'advanced' from 'advance', meaning 'to move forward'.

'foreseeably' changed from the Old English word 'foreseon', and 'advanced' from the Old French word 'avancer', eventually becoming the modern English word 'foreseeably-advanced'.

Initially, 'foreseeably' meant 'capable of being foreseen', and 'advanced' meant 'moved forward', but over time they combined to describe something predictably ahead in development.
