GetTabs looks interesting in a sense that it is personalized to you and does not require programming. The fluidity of it is super useful and this is the one aspect that I think will carry on to future iterations of AI. 

It’s kind of hard for me to put it into words, and I haven’t given it that much thought yet, but our current tooling feels like a means to and end. Tools to build what we’re looking to do, vs. just doing that thing near instantly. Apps feel like a stepping stone, the ugly details behind the actual things we want to accomplish. Future AI will likely abstract away the concepts of apps entirely. You might have an operating system of sorts tuned to your preferences and taste. It might just do the thing you’re looking to do, without involving UI - or if UI is involved, it will be fluid, easy to discard, reset, and conjure up in mere seconds, maybe even possibly with thought or trained on your routine and behavior (or even your thoughts - all of your data). 

It’s a bit hard to imagine what that looks like in practice - something has not been invented yet that will make it easier to imagine.

Agreed - your OS will just do the thing. No specific app download required.
