IMO the main pro of cloud storage is that the provider’s engineers are much better at doing backups than you are. You won’t lose your data if, like most people, you only have one copy of everything and your hard drive is destroyed.
The main con is that the provider can deny you access without warning. You probably won’t get an explanation or a real chance to appeal the decision.
So far that second thing hasn’t been a common problem for normal users but I would still keep local copies of the data which I can’t easily replace.
Putin is 72. A child born today will be too young to be a worker or a soldier by the time Putin dies. I suppose Putin may want a higher birth rate for ideological reasons but I don’t see how he would derive any practical benefit from it.
