lul what? As a linux fanboy who "speaks unix" (presumably, do I? not sure...). I find it humorous that we have gone full circle. The newest tech shit is recommending I learn almost 50 year old technology? Time for me to log off.
The point is exactly what you say: Not to have the latest tech product (e.g., grok bot, instinct, ...), but to just use powerful tools whose flexibility have been battle tested other the ages.
