Have machines come to replace humans

 1. Yes

 The answer is yes, but not yet. The reason being that we still need humans to create and produce things like software, hardware, and even food. But what does this mean? Well, it means that we have to be careful not to overuse or abuse technology. We must always remember that we are human beings first and foremost.

 2. No

 This question is a little bit harder to answer. I believe that we will eventually reach a point where machines will completely replace humans in many different aspects of our lives. For example, if we could invent a machine that was able to write a book, then we would no longer need writers. If we were able to build a machine that could do our taxes, then we would no long need accountants. And if we created a machine that could cook us a delicious meal, then we wouldn't need chefs.

 3. Maybe

 I think that maybe we will never reach a point where machines completely replace humans. As long as we continue to learn and grow, then we will always have something to offer each other.
