A space alien with a raygun and a watch knows just enough English to tell you to build a time machine "or else!"

Any attempt to persuade him otherwise just results in him pointing his raygun to his watch. Either he's ignorant, can't or won't understand, or simply doesn't care.

Software management in 2019 is still very much like this. Management has had 40 years to solve this problem, and it looks like it won't be solved in the next 40 either
