Questions & Answers about Они реализуют наши идеи.
Since реализовать is a biaspectual verb, how do we know реализуют means 'are implementing' rather than 'will implement'?
Because it is a biaspectual verb, the non-past form реализуют can serve as either the present imperfective (are implementing) or the future perfective (will implement). Without additional context words like завтра (tomorrow) or a broader narrative, a standalone sentence like this defaults to the present imperfective interpretation.
How would I say 'They will implement our ideas' then?
You can use this exact same sentence! You would just rely on the surrounding context to trigger the future perfective meaning. For example, adding a time marker makes the aspectual resolution clear: В следующем году они реализуют наши идеи (Next year they will implement our ideas).
Is реализовать a false friend? Can it mean 'to realize' as in 'to figure out'?
Yes, it is a partial false friend. Реализовать only means 'to realize' in the sense of making something real, like implementing a plan, fulfilling potential, or selling products. To say 'they realized they were wrong' (suddenly understood), you must use verbs like понять or осознать.
Why does the direct object наши идеи look like it is in the nominative case instead of the accusative?
It actually is in the accusative case! Remember that for plural nouns, the accusative case form depends on animacy. Because идея is an inanimate concept, its accusative plural form is identical to its nominative plural form. The possessive modifier наши matches this inanimate pattern as well.
