Does org mode have semantic understanding of keywords and a language AI to record my tasks for me? Then it's doomed. Does it sync in the cloud and have world class security (only storing decryption keys at rest in specialized hardware, locally on a TPM like device)? Then it's doomed. Does it have beautiful graphical interfaces for tablet, phone, and PC? Then it's doomed. Does it require you to learn how to use an antiquated text editor that only a small niche of non-programmers are using? Then it's doomed.
You can use org mode even if it is doomed to be irrelevant to normal people. It will continue to work. But it's not magic, please STOP TELLING ME IT'S MAGIC. It's not better than what's out there. There's companies sinking tons of money into todo apps and note taking apps that are integrating modern technologies that make any advantage of org mode complete obsolete in the world of advanced GUIs and language models.
