The dot-com-bubble showed us that businesses should not be valued simply because they leverage hot new technology (hold your AI comparisons...). These high-profile hacks and security failures will hopefully show us that businesses should not be considered secure simply because they stack up to other measures of value.

I would hope that in the future, a fault in a company's infrastructure security is considered as seriously as a fault in its core business model.

It's true, however there seems to be a pattern incompetence when it comes to Equifax. When the first hack happened, if my memory serves me well, they started blaming Apache struts for the security breach, which might or might not be true, however the security patch was available for month when the hack occurred.
