Is cloud computing a threat to sysadmin jobs ?

[eugene.gorelik-Re5JQEeQqe8AvxtiuMwx3w at public.gmane.org]

There were lots of discussions recently about how outsourced cloud  
computing environments, like Amazon EC2 can affect future sysadmin jobs.
As speed and reliability of internet constantly grows, more companies  
prefer to build their infrastructures in third party internet clouds  
instead of creating their own datacenter environments.

Does it mean that building cloud-based environment require less sysadmin  
help that building traditional one ?
I am curious what other people think about that ?
