Let’s stay with the (at minimum) low quality solution: What would do someone without IA?
- ask on a forum (Facebook, Reddit, askHN, spécialises forums…)
- ask a neighbor if he knows someone knowledgeable (2 or 3 relations can lead you to many experts)
- go to the library. Time consuming but you might learn something else too and improve knowledge and IQ
- think again about the problem (ask Why? Many times, think out of the box…)
