Showing URLs is essential. Google isn't able to determine what sites are safe. You can test it by signing up for a lot of Google Alerts. I get fed many shady URLs in Google Alerts and have clicked on some of them accidentally because the URLs aren't displayed in the emails anymore. If the URLs had been clearly displayed, I wouldn't have clicked on them.
A tool that warns people when something appears wrong with a URL would be useful, but hiding URLs from users would be a terrible idea. It will create a generation of people who don't even have the capability to visually scan a URL to see if it's safe.
Technology shouldn't be dumbed-down for people so much that many people who are capable of learning how it works will never see enough of the details to become curious. I've even met professional web developers who don't understand URLs well due to the current URL trimming in most browsers.
