I love that quote from Linus. In fact, we had it in mind when we designed TigerBeetle [1][2], a financial accounting database to do a million financial transactions a second. We started with the data structures, made sure that these were one or two cache lines to reduce cache misses and perfectly aligned to eliminate false sharing, and then we added built-in accounting primitives to move the code to the data, instead of the data back and forth across the network to the code, which is how these kinds of balance tracking systems that we were working with before were typically implemented. The result is much simpler, a perfect replicated state machine, and also much safer, because the business logic and data are executed within the state machine, protected by the distributed consensus protocol (Viewstamped Replication Revisited by Liskov and Cowling), rather than a mess of SQL transactions spanning multiple distributed systems, all with different clocks.

The community is amazing, deeply talented, with great taste, and at the vanguard of where things are going for these kinds of systems.
