Modern fighters: why so similar?

Let’s make it simple. According to aircraft designers (often accused of copying from other projects….), modern fighters are similar one another because computers model more or less in the same way the shapes required to achieve the requested performances. Maybe. At the end of the day, although showing a certain degree of similarity at first glance, depending on the way a computer uses the law of physics and aerodynamics to solve a common problem, at a more in-depth look, each fighter shows its own peculiarities, as a consequences of the “personal touch” of the designing team.
