I agree that my healthcare interactions have been improved by Epic. But Epic has no motivation to keep improving, because they control most [1] of the US medical records, and once a hospital is a client, its practically impossible for the hospital to also try a competitor's record management system (medical records are not unique in the enormous cost of switching between systems). So even while we can be glad for mychart we will suffer the increasing downsides of Epic's practical monopoly, without even knowing how much better it could be.
