Whilst that is true, it doesn't have to be that way. If from day one, liability for software bugs lead back to whomever wrote the code, then the world would be a much different place.
For one thing, we would be much more conservative in how we wrote code. Libraries would be vetted, with insurance contracts attached to them. Programming languages would not allow for dynamic data, type coercion, or weak typing. In the 80s, rather than C rising to prominence, Ada would have. Haskell would be our generations Javascript, and XHTML would have won over HTML5 simple because guessing how rendering should work would open up a browser maker to high fines and lawsuits.
We'd have to rewrite our entire software stack from the ground up. It's not impossible, but we'd have to view it as a multi-decade transition like how the chemical industry was slowly forced to not use heavily polluting procedures.
Millions of malicious people constantly attacking it with cheap equipment from a distance with little chance of being caught doing so?
