https://github.com/walmartlabs/lacinia What I know about tech at Walmart is the Clojure lib above, which is the de facto graphql lib for the language today. Point being that tech existed for a while before big tech, and imo is going to be ever more present in more sectors of the economy. MAANG seems most relevant today in the capacities they gain from the amount of data they collect, and the importance of AWS for infrastructure (unless that's overrated, as it's starting to look like it is). What I know for sure is that the obsession with big tech as a representation of tech as a whole gives a distorted picture of things. Getting closer to reality in this matter is one big challenge.
