I argued with my stepfather about the internet in much the same way in 1987. I told him to go all in on it. I asked if I could use my college money.

"There's no value in it. It's just data."

It's okay if you don't get it yet. Your fear is understandable and in the correct cases, understandable (much like fears internet would make illegal activity easier... Which it did)

But you must at least know enough to argue the correct cases and from what you've presented it's clear you are relying on intuition and folksy wisdom rather than research.

You're not incorrect... Just not specific enough.

Regardless, it's here to stay despite your fears. Things are neither good nor evil... It's how we use them.

If you fear, start figuring out how to use it for good.
