I don't subscribe to this rose-tinted point of view, especially if you look at all this beautiful tech from the security standpoint.
Most of the tech we deal with today was originally designed without security concerns. In most cases, security is an afterthought.
So much for sitting back and taking a break.
"The fundamental principle of science, the definition almost, is this: the sole test of the validity of any idea is experiment." -- Richard P. Feynman
