Hoare - The Emperor's Old Clothes

The Emperor's Old Clothes by C. A. R. Hoare
What was wrong with ALGOL and how those mistakes has been planned to avoid in ADA. But that plan failed - at least at the time original paper has been published.

An interesting quote:

And so, the best of my advice to the originators and designers of ADA has been ignored. In this last resort, I appeal to you, representatives of the programming profession in the United States, and citizens concerned with the welfare and safety of your own country and of mankind: Do not allow this language in its present state to be used in applications where reliability is critical, i.e., nuclear power stations, cruise missiles, early warning systems, anti-ballistic missile defense systems. The next rocket to go astray as a result of a programming language error may not be an exploratory space rocket on a harmless trip to Venus: It may be a nuclear warhead exploding over one of our own cities. An unreliable programming language generating unreliable programs constitutes a far greater risk to our environment and to our society than unsafe cars, toxic pesticides, or accidents at nuclear power stations. Be vigilant to reduce that risk, not to increase it.
