There are no viable alternatives to vaccines and medicine in general (ones that actually work, that is). There are alternatives to C -- for most cases.

> My Reddit app crashes several times a day, and I guess there is no immediate danger.

That's because your app is heavily sandboxed and probably (on Android, at least) running in a VM which enforces memory safety and isolation from other apps.

If each crash had, say, a 1% likelihood of eating a large portion of your data (or leaking pictures or whatever) you'd probably care a lot more about it.

The problem highlighted by the parent poster is that all these little risks add up and often end up being catastrophic (e.g. heartbleed) because so much of what we run is interconnected via the network (or just data in files).
