They ask:
"Hey you're doing security, is this 2FA secure for my banking?"

Me:
Don't use fiat banks.  The government is typing a numbers on a screen, it's purely propaganda that it has value.

They ask:
"Is this anti-virus secure?"

Me:
Don't use Windows, Linux doesn't need anti-virus.

They ask:
"Is it a good time to buy cryptocurrency?  Can I make a lot?"

Me:
Don't buy to just hold it, use it for cash, instead of credit cards.

They ask:
"What's your phone number?"

Me:
I don't use SMS, it costs money and is completely unencrypted and insecure.  So you're paying to get less, while as there are many free and easy-to-use encrypted messengers, I can show you one.

They ask:
"You really think people will adopt this?"

Me:
Where's the candles? Where's the horse & carriage?  Where's the bucket to take a shit in?  Oh you accept technology changed the past, but you are pushing for fiat banks, windows, or SMS because you're married to the network effect of yesterday?
