Mikhail Kalashnikov designed the rifle for the Russian army. It was a simple and cheap automatic rifle that caused more deaths than any other assault rifle.
Kalashnikov later wrote in a letter to the head of the Russian Orthodox church, "If my rifle claimed people's lives, can it be that I…, an Orthodox believer, am to blame for their deaths, even if they are my enemies?"
Tim Berners Lee developed HTML and created the World Wide Web, but his major regret relates to the '//' at the beginning of every web address.
"Really, if you think about it, it doesn't need the //. I could have designed it not to have the //," he said.
Working as an employee of web host Tripod, Ethan Zuckerman wrote the code to launch the pesky pop-up add.
In an essay entitled "The Internet's Original Sin," he took full responsibility for the hated tool. He later explained that he was sorry. Their intentions were good.
Flappy Bird was a crude and simple game that proved to be hugely addictive. After 50 million downloads and advertising revenue of around $45,000 a day, creator Dong Nguyen had enough and withdrew it from the app stores.
The game attracted the press and Nguyen was besieged with calls, tweets, and emails. He tweeted, "I cannot take this anymore."
Bob Propst introduced America to the open-plan office along with the office cubicle.
Companies saw his invention as a way to save money. Propst came to regret his creation, saying cubiclizing people in modern corporations is "monolithic insanity."
Vincent Connare, the designer of the font Comic Sans, said, "If you love it, you don't know much about typography. If you hate it, you really don't know much about typography, either, and you should get another hobby."
Connare's point is that Comic Sans is overused and misused. It was designed for a Microsoft application aimed at children to replace Times New Roman in speech bubbles.
Tom Karen designed the Raleigh's Chopper, one of Raleigh's best-selling bikes in the 1970s. It was loved for its comfortable saddle, laid-back seating, and Harley Davidson-Esque handlebars.
However, Tom Karen describes it as "terribly heavy so you wouldn't want to ride it very far."
Kamran Loghman worked for the FBI and helped turn pepper spray into weapons grade material. He also wrote a user guide for police departments.
In 2011, police sprayed pepper spray on docile protestors. Longman's reaction was, "I have never seen such an inappropriate and improper use of chemical agents."
John Sylvan's invention of coffee pouches gave rise to systems like Nespresso and Tassimo and make it very easy to grab a caffeine fix.
"I feel bad sometimes that I ever did it," he said a few years ago. "It's ... a single-serve delivery mechanism for an addictive substance."

Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.
This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!
Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.
Don’t look further if you love learning new things. A refreshing concept that provides quick ideas for busy thought leaders.
Great for quick bits of information and interesting ideas around whatever topics you are interested in. Visually, it looks great as well.
I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
Even five minutes a day will improve your thinking. I've come across new ideas and learnt to improve existing ways to become more motivated, confident and happier.
Brilliant. It feels fresh and encouraging. So many interesting pieces of information that are just enough to absorb and apply. So happy I found this.
