This is kind of scarier to me than AI taking over our jobs or becoming sentient and killing everyone.
While at the same time I absolutely see it like this. Tools like this giving you immense more space for productivity. Not for multitasking probably. But for being aware of things to keep track off, while multitasking.
I though vr and mixed reality was crap because i had only really used it with a single window. Which is not better than just having a screen.
Proceed with caution, humanity.
