It works with "future" as well. In your exmaple it is just an aspect of time as oppsed to past and present, and everyone knows there's only one future as a temporal direction. But "Does the combustion engine have a future?" is a question about a non-introduced concept of the specific future of a specific item, which can then be answered like "yes, the future of this engine lies in..." etc.

And I said "the specific future of a specific item" because there might be any number of items, therefore "a specific item", but once I select that item it can only have one specific future, therefore ""the". The definite article is used for concepts which are further defined. Any item has a specific future, but a specific item has the specific future it will turn out to have had.

Yeah, the mind boggles... I'm glad I was born to the concept of articles, and much more complicated ones than the English articles to boot, but I righteously suffer for that by not being born to the concept of verb aspect.
