Re: "it is trial and error which provides improvement"
"Yes, as long as you do it in your labs and test rigs, maybe on yourself, not on people's lives. Especially when "error" means big damages and losses, even of lives."
And so in this cotton wool dream world we have nothing. Glad I dont live there. The failure of windfarms was demonstrated through the real world. The improvement of solar through the real world. Hell the reason we have mobile phones in our pockets anywhere near as small as we have is due to real world use of the huge bricks with huge batteries. A lab only gets you so far.
"hey, let's make this without thinking how to build it following known rules"
Where did that come from? Next they will have an evil grin and curled moustache. The automated car is based on known rules, yet there is plenty of unknown that simply requires working out in the real world (they are on the real roads already).
"BTW, the Internet never solved its own problems - actually is just creating more which aren't addressed, and are just growing"
And isnt it awful. We communicate on forums, chat, video. We transfer files with geographical distance being of limited interest. We shop in the comfort of our own homes and many people are employed purely due to this wonderful technology. Would you honestly prefer we didnt have it and it sat in a lab being neutered until it became impossible to deploy, or do you like writing your comments on el reg?
"Exactly because nobody back then thought about security."
Really? The purpose of the internet was nothing to do with where we are now, it was about reliable communication which is does well. Everything else built on top of it and in answer to the question "Should we repeat the same errors" feckin hell yes because those mistakes gave me my job, interests, information on further interests, comfort, convenience and makes people happy.
