I'll note that I have no disagreement with the above quote, even though
I don't agree with Dennett's intentional stance.

The difference is trivial. If you don't see it as trivial, then you
probably have the wrong idea about cause.

But what is meant by "inner life". The intentional stance has to do
with inner operations, and whether those can be said to constitute an
inner life is of no importance. What matters is that those inner
operations manage the external behavior.

Again, I think you are misusing "causal" here. That "directly caused
by a prior condition" part is just as applicable to a person as it is
to a mechanical robot.
I have no doubt that a computer has some sort of inner life. As a
computer scientist, I program some of that inner life. Presumably you
will deny that "inner life" is the appropriate terminology, but that is
not relevant. What matters is that what goes on inside manages the
external behavior.
The problem for a computer is whether it has an outer life. That is,
the important question should be whether the inner life (inner
operations) properly connect with the external world.
Take that traffic light down the street. Its inner operations do
connect with the outer world. And we know that they connect because
traffic engineers created the connections. So there is a traffic
sensor under the road signalling information about the traffic to the
computer that controls the light.
But now suppose that there is an accident that blocks the north bound
lanes. So the northbound traffic is diverted to use the southbound
lanes (while heading north). We no longer have any confidence that the
traffic light is connecting with the external world, because we know
that the sensors it uses are in the wrong place to detect the north
bound traffic. So we call in a policeman to manage the traffic flow.
And we have no problem trusting that the policeman's inner processes
suitably connect to the external world, even though our traffic
engineers did not design those connections for the policeman.
