At present, technology has reached a high peak that human never been there before, which, of course, boomed economy to a top of its history. Side effects of these, geopolitical tensions and global heating were resulted, of which, I think cannot be solved by technology itself because of the limitation of the overall energy transform efficiency--each type of it has drawbacks. For options, I believe, the mankind should be self-disciplined, that is, try to live a frugal life, control the population. A large part of energy consumption is transportation. We supply ourselves mostly by local products, no good to be supplied by global companies. Use technology that only necessary. Modern is not everything and it has to be limited at a best point. Extreme capitalism may ruin our planet finally.
