It's only possible with a very different set of tradeoffs around risk and innovation than are the norm in software. It takes NASA-grade layers of slow development processes to be 100% certain that there will never be any incidents. Most companies, most developers, and most consumers would not be happy with the cost and speed this would result in. In short: it's not that it's impossible. We know how to do it. It just comes with a cost attached that nobody wants to pay.
