Comment by Ellundril on Isekai Teni shitara Aiken ga Saikyou ni narimashita - Silver Fenrir to Ore ga Isekai Kurashi wo Hajimetara - Chapter 12

@Ellundril "sufficiently advanced technology is indistinguishable from magic to those who do not understand it" is a good quote to use when comparing magic and technology

@Ellundril depend on the magic system. Few magic system actually have it exclusively originate from the person. More commonly, magic is everywhere like the one in this series. People can utilize their own pool or use the surrounding mana with a ritual or object. Magic is also often use as an add-on like physical enhancement, or enchantment. The quote is about the end results rather than the working of the system. A sufficiently advance tech can produce result that look indistinguishable from magic. A teleport belt in sci-fi is basically the same as a teleport spell in fantasy, different mechanic sure, but same result. Plasma cannon = fireball spell.
