18.7.1 Future to express doubts (and assumptions)

In the German language there is a funny extra use for the future construction: the expression of doubt or an assumption. In these doubts and assumptions, there is the grammatical form of future tenses but no time mentioned.

Er wird wissen, was er tut. = (I assume, I doubt that) he knows what he is doing.
Sie werden wohl das ganze Geld ausgegeben haben. = (I suppose) they have spent all their money.
