Why Does My Phd Advisor Insist I Master Vim?

Why does my PhD advisor insist I master Vim, write manuscripts in LaTeX and code up all my statistics and data structures myself in C?

Condensed C & DSA quickly learn the following. If-else and nested if-else construct in C for loop (thoroughly) while loop and do while loop Structures Arrays 1D, 2D & 3D Character Arrays & String manipulation Call by Value Vs Call by Reference Pointers Pointer-to-pointer Recursive functions. How t work, Types of recursive functions Understand , practice and memorize these programs/implementations in C (or language of your choice). Binary Search (depends on sorting, because is done on a sorted list) Quick Sort Bubble Sort Merge Sort Heap Sort Insertion Sort Selection Sort Lists (SLL, DLL, CLL) Stack and Multi-Stack Queue, Circular Queue, Double ended Queue and Multi-queue Binary Search Tree (Ops. Insertion, Traversal ( all three), Searching) Graph Representation DFS and BFS Prim’s Algorithm Kruskal’s Algorithm Learning this much is possible in 3 months. Take help of a guide or the sites like geeks4geeks . 90% of the softwares you will be developing in future as software developers/engineers will involve these programmes only (as componets/building-blocks).
