Everything evaluates. Nothing remains without changes. There have been languages and civilizations that have been vanished and replaced with new ones.
Databases in the next decades or further than that demands actions that Access and VBA can not be an answer to them. Access will grow to its limits and then when it can not respond to more evaluation, because its based programming is limited and can not answer to newer features, it dies and will be replace to a newer one that can be an answer to the newer needs. It's just a matter of time.
