This thought has a very narrow perspective. During the space program, a few million rows was very large. Today, you have better tools so a few million rows is small to you. But someone else who works on Fugaku has tools that you don't have and will find that your "large" amount of data is small to them -- they also get to use the electrical equivalent of 20,000 homes to process that data. Most people today don't have the computing tools that you do. Yes, a consumer laptop running Numpy can process it quickly. But they have Excel, not Numpy...and Excel cannot process millions of rows. So in the context of the tools they have, it is a large table.
