Good thoughts Andrew,

I mostly like the definition of NNGroup about CX and UX.

"They both encompass all aspects of the end-user's interaction with the company, its services, and its products."

When UX is only talking about Digital Interaction, CX is the whole process, Offline - Online.

At the end of the day, a good experience customer requires we do good on all perspective, not only digital interaction but also offline service.
