Future Perfect and the use of it in the subject position can be employed to make predictions about actions that will be finished before a specific time in the future. This tense is commonly used with time expressions like "by 2020" or "before the end of the century." An example sentence would be: "By 2050, Al will have been designed by scientists." The certainty of these predictions can be adjusted by using modals such as "may," "might," or "could" instead of "will." For instance, "By 2070, the researchers may/might/could have implanted A-chips directly into the human brain." It is also possible to create predictions using the pronoun "it" as the subject.

important to note that the Future Perfect tense is formed by using the auxiliary verb "will" or "shall" + the auxiliary verb "have" + the past participle of the main verb.The Future Perfect tense is used to express actions that will be completed or finished before a specific time in the future. It is often used to make predictions about future events and actions. By using time expressions like "by 2020" or "before the end of the century," we can specify the timeframe for the completion of the action.
For example, let"s take the sentence "By 2050, Al will have been designed by scientists." In this sentence, we are predicting that by the year 2050, scientists will have finished designing Al (presumably referring to an artificial intelligence system or a robot). This implies that the designing process will be completed before 2050.
To adjust the certainty of these predictions, we can use modals such as "may," "might," or "could" instead of the more definite modal "will." For instance, "By 2070, the researchers may/might/could have implanted A-chips directly into the human brain." This means that there is some uncertainty or possibility that by the year 2070, researchers will have implanted A-chips into the human brain. The choice of modal depends on the level of certainty or probability assigned to the prediction.
In summary, the Future Perfect tense is used to make predictions about actions that will be completed before a specific time in the future. It is formed using "will" or "shall" + "have" + past participle and can be adjusted for certainty using modals like "may," "might," or "could." Time expressions help to specify the timeframe for the completion of the action.
