That was a world where the user base was much more limited and devices were less capable. Now we have children, grandparents, educated, and uneducated users with access to web connected devices. These devices now contain everything about you. Compromise of a device can destroy someone’s life.
Not only that, but compromise of a device can cause collateral damage to other devices on the same network.
We now have to cater to every user. Not just to the technologically adept. Look at what people believe on social media. The bar is so low to con people into compromising their device.
