Hawaii believes that we are still playing games with the phones. Is the HarmonyOS going to be supported by your bank anytime soon? NO. Is it going to be supported by major and important everyday applications like facebook, viber, whatapp, slack, teams etc? NO. When those application are willing to support the new OS? No, Unless Hawaii pays for the development or immediately accumulates let's say 15% of userbase. It's going to be fun though. Another Nokia/Microsoft to grab popcorn and watch freefalling.
