The article argues that the era of Big Data is over, as most organizations do not have massive amounts of data and the focus should shift from handling large data sizes to making better decisions with the data they have. The author, who previously worked on Google BigQuery, claims that even large enterprises often have moderate data sizes and that the majority of customers have less than a terabyte of data. The article also discusses how the separation of storage and compute in modern cloud data platforms has reduced the need for large-scale data processing. The author suggests that the emphasis on Big Data has been misplaced and that it is time to move on from this paradigm.
