Quote from VBprogrammer:

You're thinking way too tin hat.

I very, very rarely resort to ad hominem, least of all on HN, but your nickname says it all (if indeed VB refers to Visual Basic). Far too many computer problems of yore were created by VB programmers not being nearly "tin hat" enough. When engineering systems which can damage other systems or cause bodily harm, one's responsibility is to anticipate, mitigate, and prevent the worst case scenario to the maximum extent possible.

[VBprogrammer]

Well VBprogrammer is a moniker I've used since I was 14. I now work for a company building websites which have thousands of hits a minute, require PCI compliance and use a variety of tools, none of which are Visual Basic.

Given that you resorted to ad hominem I assume you have no other reasonable arguments against what I said.

I understand the desire to keep an old handle. Regarding your last paragraph, I believe my second sentence stands on its own, and that others have said anything else I might care to express. Basically, with something that has the potential to maim and kill (like self-driving cars), I expect engineers to take every precaution.
