Assuming this is going to save someone 10ns per query in the end and I spent 150h on coding and writing this up, we only(?) need around 10^14 queries to make it

Assuming this is going to save someone 10ns per query in the end and I spent 150h on coding and writing this up, we only(?) need around 10^14 queries to make it worth it! But yes, as new technologies stack up, we achieve exponential growth in throughput in the end, which usually enables new science :)
