هذا هو رد مؤلف الكتاب مع احترامى للجميع::::

Sec 3 SB, page 96: Why didn’t you use the future perfect tense in this sentence? “English will be
spoken by half the world’s population by 2050.” I have been taught that “by + year” is a keyword for the future perfect.

When I was studying for my master’s degree in TEFL, I never came across this “keyword” method of teaching. In fact, I never saw it until I came to Egypt. It is one of the features of “cookbook English” — without thinking of the meaning, students memorize and apply “rules” that are incorrectly stated or overgeneralized and which lead to monstrosities of language.
By + year can go with any number of verb tenses. The future perfect is used to talk about something that will be completed by a time in the future. English will be spoken is not something that will be completed then. It will be an ongoing activity, and that is why the future perfect is not used.

Thank you Mr .This a very strong evidence
