First couple of tasks are really easy, but difficulty increases over time and so does time needed to solve them.
Someone who is currently learning about loops might not be able to solve these on their own, but with someone else's help they might learn lots of useful concepts (e.g. linked lists, bfs, basic asm, how to code efficiently...) and try to apply them.
AoC are solving usually those who are quite familiar with programming and want to learn a new language or to compete with colleagues.
