All technological advances must be oriented and directed for the benefit of humanity, not to the detriment of it. It is worrying that attempts are being made to replace human intelligence and man's work with artificial intelligence and robotics. In the end, everything will be automated, technology mined? and humanity? I don't even want to dream about it, and I believe that nothing can replace the burden of feelings that human beings bring with them. I totally agree with you when it comes to the use of drones, that's why I like your phrase: "They can at least be used to deliver books and supplies to students!" Excellent publication, @techblogger. Thank you, @adsactly.
