On: What does a CTO actually do?

[spott]

Neither role is well enough defined to make these kinds of statements.

The CTO could be the top of the IT org, and have nothing to do with research. There could be a Chief Scientist.

These roles are defined by the executive team as they are working. They are the only ones that can define them beyond a bunch of gross generalizations.

The topic is literally one that is to define the role, my man. I don't understand your criticism.
