Inevitably, you have to wonder if Bill not only feels regretful but also a little embarrassed. It’s not entirely his fault either. Fifteen years ago, there was very little research into passwords and information security, while researchers can now draw on millions upon millions of examples. Bill also wasn’t the only one to come up with some regrettable ideas in the early days of the web, either. Remember pop-ads, the scourge of the mid-aughts internet? The inventor of those is super sorry as well . Oh, and the confusing, unnecessary double slash in web addresses? The inventor of that idea (and the web itself) Tim Berners-Lee is also sorry .
