gradually become or is gradually becoming
The two sentences below are in the present simple tense. The tense is used, because, as I remember from many grammar books, the first one is about something that happens regularly (is in "The sun rises in the morning and sets at evening."). The second one is a book review.
"After working for a while, getting a car gradually becomes more of a priority."
"Although his pursuer searches for the body, it gradually becomes clear the man has vanished not through trickery but through divine intervention."
And that's fine.
My problem is with this sentence:
"Aramaic gradually becomes the language of outer life..."
I can't find an explanaton why the present tense is used here
In my opinion the function of 'to become' in the 'Aramic' example is similar to
"Lenovo is gradually becoming becoming more of a mobile firm..."
So, the present progressive tense should be used in it.
What do you think?
