This. As people collect more and more personal data about themselves, which they do unconsciously already, the only thing that's missing is an offline system (software) on the local computer/device that enables processing and making sense of all this data, ideally _without_ companies also obtaining the data. Such software appears to be possible in the near future with all these neural network, NLP, image processing, .. systems. I think developers of open-source apps ought to agree on some standard data format so that data from different apps/sources can easily be aggregated without additional processing. The problem is: commercial apps/platforms don't have any incentive to enable private personal data collection and companies will always have a head start over the individual in different ways: amount of data, processing power, brain power, .. And people don't appear to realize that companies are constantly optimising against the individual and therefor the individual needs better tools to gain a better position.
