If we walked into a room and I asked you to point to the Wi‑Fi, you’d probably laugh, or glance around, unsure what to indicate. There’s nothing to see. There’s no colors, no waves, no movement. And yet, in that same space, messages fly, videos stream, voices cross oceans in real time.

How can something invisible carry so much? You don’t see Wi‑Fi, but you don’t deny it exists. So why do we insist on seeing to believe?

Now step outside.
