Despite appearances, dynamicland isn't about any particular paradigm on its own. It's a set of values and a way of looking at media that come together to create computer-literate communities and even culture.
This is obviously a bit vague, especially if you look at all the things they're doing with the cameras and the projectors and the dots and all that. There's nothing stopping anyone "running" dynamicland on anything else.
It's a completely different way of looking at computers, and it's basically saying "monitors, keyboards, mice, projectors, smartphones, tablets, laptops, vr headsets and xr headsets are all different kinds of ways to experience computation in the flesh. We want to explore what happens when we change the fundamental assumptions that computing is something you do (alone) in front of 'a computer'. What could computing look like if it was reimagined from the ground up, and we used people instead of person as our target audience, space instead of product, extensions of existing media rather than inventing new media, literacy instead of profession".
It's difficult to really explain in one go, I've been following Bret Victor since before he even started ok CDG
Regardless, I think it's the future for precisely one reason; it's easier, cheaper and more powerful. People can and people will integrate it with all the high tech stuff that we already have, that includes powerful desktops, vr, smartphones etc.
