MATLAB
MATLAB is a matrix playground that lets you feel like you control the universe with a few lines of code. It harbors an endless jungle of built-in functions and the licensing underworld, while custom scripts disappear into its black hole. Caught between GUI and command window, developers become slaves to visuals and numbers. When it works, you are hailed as a genius; when it crashes, you plunge into debugging hell. Purchasing toolboxes initiates a duel with your budget.
