Predicting the Future Perfect and using it in subject position The Future Perfect is utilized for making predictions

There are a couple of things to consider when using the Future Perfect tense to make predictions. First, the Future Perfect is used to talk about actions or events that will be completed before a specific time in the future. It is often accompanied by time indicators such as "by 2020" or "before the end of the century" to indicate when the action will be completed.

For example, let"s say we want to predict when AI will be designed by scientists. We can use the Future Perfect tense and say, "Scientists will have designed AI by 2050." This means that by the year 2050, the process of designing AI will be completed.

To modify the certainty of these predictions, we can use verbs like "may", "might", or "could" instead of "will". For example, we can say, "By 2070, the researchers may/might/could have implanted chips directly into the human brain." This indicates that there is some uncertainty about whether the researchers will actually be able to achieve this by 2070.

It"s important to note that predictions can also be formed without using the Future Perfect tense. For example, we can simply say, "Scientists will design AI by 2050" without using the Future Perfect. However, using the Future Perfect adds a sense of completion and emphasizes that the action will be fully finished before a specific time in the future.

So, 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 often accompanied by time indicators, and the certainty of these predictions can be modified by using verbs like "may", "might", or "could".
