In an exercise (it deals with a happy future world) about putting verbs in future there are:
1) Людям не...[быть нужным] очки.
2) Детям не ...[быть нужным] школы: они будут заниматься дома на компютере.
And as better solutions
1) Людям не будут нужным очки.
2) Детям не будут нужным школы...
It would not be better in both phrases " нужными", according with subjects of the verbs? I know the proverb "Better necessary than free" and I don't know if the use of нужным is as neuter: "Glasses will not be something necessary for people". Can you make it clear for me? Thanks
