Alerts are most important, that's why paper doesn't work for me. I just write everything in my calender app in my phone.
As for tasks tracking, it’s all lists. And a daily/weekly/monthly review is enough for me.
Hence it makes it easier if theyre all under the same roof.
If you put non-date-specific TODOs in your calendar, then as soon as the number of TODOs in that system becomes overwhelming, you stop looking at your calendar and start missing appointments & truly date specific reminders.
If you put date-dependent TODOs in your task tracking system, then every time you look at it you see a bunch of stuff you can't move on and you quickly lose effectiveness.
If something is dependent on a specific date or time, either because it is an appointment or because it is nonactionable until then, put it in a calendar or tickler file. If not, keep it the hell away from your calendar and put it on a TODO list (plain text file is fine). This keeps both systems effective.
We have not even started combining digital an real world, and the last few idea, e.g. from Meta, were devoid of anything useful, showing how little actually useful imagination some super-rich have, putting so many resources into bad or even destructive ideas when sooo much useful stuff needs to happen. We still have this tiny viewport, behind which another world - our digital world - awaits, and people think it's normal that we use this tiny port and awkward indirect devices (mouse) to manipulate things in there. We could do soooo much better soon!
Okay, the access device still is missing. Few people want to wear the current generation of AR devices. But that just shows that neuro-computer interface needs investment on the level of AI, it's not magic (actual neurons are just very complex to work with, never mind finding the right one's to connect to), we could slowly build something there.
Somebody asked what the advantage is of having this computerized instead of actual matter, e.g. physical paper notes. It's all the general computer advantages of course, like sharing stuff. Never mind being able to reorganize everything in an instant.
Imagine having a software project not viewed with one tiny viewport, but like a physical project, even over several rooms. You don't need to click, you go to the place representing some module and physically (virtually physically) take out the code, edit with your fingers. Watch the data flow around you. Have a bunch of flying piranhas show up when something goes wrong. Work with all your body in a real 3D space instead of sitting in a chair all day, all week, all month, all life, watching that vast digital world and/or just your project through that tiny viewport.
