How?

In the 90's most software was closed source but cracks/trainer were always available.

Even for Rayman that had multiple (26?) cd-check during the game.

Security is mainly slowing the attacker because there's a maximum amount of stuff a human can do in 24hours. But now if you can simulate thousands of human attacking a system in different ways, it will crack.

Just like many stores have lock on their doors and, insurance if someone breaks the lock.

I'm guessing data security insurance will become a huge market in the years to come.
