Why Achieving Light-speed Requires Infinite Energy: Matter-waves

This topic has been done ad nauseam.
However, I feel of the videos I've seen, they either focus too much on relativity and just time and space ceasing to exist at such a speed. Or equations showing that you would require infinite energy or have infinite mass (which is an incorrect way of looking at it) without really explaining the intuition as to WHY this happens.

It's probably not necessary to need to know about quantum physics to understand this phenomenon, but hopefully it helps expand your view on the universe.
