Would you rather them explain it in terms of pipes and plumbing?
I believe the idea of magic being a flow of energy (or mana) has been long established. Circuitry is just a much better way of explaining it that flows of water or air since we don't see flowing water doing amazing things on a daily basis. And charging yourself like a battery sounds so much more natural to us humanoids that filling ourselves with magic like a damn.
That said, I wouldn't mind a completely new onlook to magic.
But we have already pushed the limits with technology to the point where I wonder if there will even be an allure for magic in the youth of tomorrow. Space, temporal, and alchemy(and create/destroy matter) are the only types of magic I can think of that are still too difficult for us to be practical. Alchemy cost way to much, the world will go bankrupt before you make a pot of gold. Space/temporal are both held up by how difficult it is to get things to light speed (not to mention doing it in a timely manner without destroying the thing your transporting). We will probably have to settle with robots for telepathy, but controlling them with our mind is already possible, though not very elegant without implants. Any other type of magic seems to just be our current technology in a bottle (everything is better in a bottle). Or put into grand scale bc who doesn't want to cook everything inside the entire forest with a fire blast... wait, we have that. Its called a forest fire. Magicians, ADVANCE!
I sincerely believe we will have the floating screens/GUIs/HUDs that we have always dreamed about in the near future, floating physical screens are probably asking for too much, but head-mounted 3d HUDs or maybe actual 3d projections (not holograms, no enclosure) with touch feedback (from a glove) seems entirely possible. We already have the base for it, just lacking elegance and appeal necessary for mass adoption.
