If you are going to make companies, corporations, actually responsible for the safety of other people's lives, then if they fail in their duty, the only thing to prevent them failing in their duty is the fear that they would be put behind bars.
Everything changes as you get older - your mind, your body, the way you view the world.
You can always improve on something, the technology is different today, but I would leave it well alone. If there was something that was incomplete, that might be interesting... because I do that on my website.
