I think that people in future will forget how to communicate with each other, they won't talk face-to-face. They'll have no time and great need in it. I think that much will depend on the Internet, and if we always use it, we'll be always very stressful, rude, impolite, and it'll annoy other people. Or maybe scientists will invent such gadgets which will read our thoughts and people won't use words but they will just share their thoughts.
Думаю, что люди в будущем забудут, как общаться друг с другом, не будут разговаривать лицом к лицу. У них не будет на это времени и большой нужды. Я думаю, что многое будет зависеть от интернета, и если мы всегда будем им пользоваться, мы всегда будем очень подвержены стрессам, будем грубыми, невежливыми, и это будет раздражать других людей. Или, может быть, ученые изобретут такие гаджеты, которые будут читать наши мысли, и люди не будут использовать слова, а просто будут делиться своими мыслями.
