I'm still adamant about the fact that the "cloud" is a racket.
Sure, it decreases the time necessary to get something up running, but the promises of cheaper/easier to manage/more reliable have turned out to be false. Instead of paying x on sysadmin salaries, you pay 5x to mega corps and you lose ownership of all your data and infrastructure.
I think it's bad for the environment, bad for industry practices and bad for wealth accumulation & inequality.
