The industry has a lot more experience at making reliable ICE drivetrains, which helps to offset the increased complexity. After another decade or two they should be able to make the same reliability gains for electric ones. It may also be the case that everything is reliable enough for that to no longer be a significant differentiator between brands, and development money will be spent elsewhere.
