it just clicks with me, i like the syntax of the language or i believe it may solve important problems (e.q. AI helping with cancer cures, helping engineers design propulsion, improve loneliness etc). Existing documentation was important too back in the days before 2023 and the AI boom, for example asking question about c# on stackoverflow is one thing but asking about the Ring programming language totally different. Finally: versatility of language, i tend to avoid limited purpose languages like say perl or ruby which may be amazing idk but lack of gui tools, ai ecosystem, gaming development, app development etc i'd rather avoid them.
