I want Apple pie.

Nothing to be "depressed" about. Happens all the time.

"Happens all the time" is a reason not to be depressed? I think "landscape changes" take place because someone/some group got tired of being depressed and actively sought some sort of change.

OTOH, this is an excellent example of the advantages of being small and nimble - you can adapt quickly while the big boys are stuck struggling.

What? The big boys are eating Apple pie because they, I assume, had an easier time getting to the table than the small and nimble.
