Consider an older technology that became fundamental to much of daily life a century or two ago: writing. After a few millennia where literacy was a specialized skill, we pretty quickly transitioned to a society where it was essential for common activities. Rather than make sure everything had pictures and such to accommodate the illiterate, we tried to make it so that the entire population is literate, and came pretty close to succeeding. There are people who just outright can't read for whatever reason, but they're a very small minority and we aim to accommodate them by giving them assistance so they can get by in a literate world, rather than changing the world so you don't need to be able to read to live a normal life.

Rather than saying that half the population (a low estimate, I believe, for how many people will fall prey to malware in an anything-goes world) should abandon this technology, we should work to make it so they don't have to, with some combination of education and technological measures.
