In a more strict sense being "good with computers" involves programming the machine, which requires a certain type of access to the machine and its resources. Provided, we're not dealing with bare metal, this means access and intimacy with a certain operating environment – which may be subject to change, as preferences for languages change, as do operating systems or the underlying hardware. In a broader sense, being "good with computers" may mean a certain familiarity with a certain type of paradigm of interaction, as embodied in a certain suite of applications, which may and will be subject to change, as well. So nobody is "good with computers" per se.
