"fantasize about a "universal" DE that can scale seamlessly from 4" phone to 40" TV" Its possible this is an inherently inappropriate goal. So many non-computer things fail to scale over a mere 10:1 ratio of size that assuming a constant UI is probably inherently the wrong goal rather than the correct goal just as a default guess. Some aspects are OK. The scribbled notes on the back of the ATM receipt in my wallet are made with the same character glyphs as I see on CAD blueprints. But the UI and technology are overall very different, because the size and job requirements are very different. Ramming one into the shell of another wouldn't be a win. Look at the ergonomics, if nothing else. I recently have the technological capability to make a wheelbarrow the size of a garden trowel, and make a garden trowel the size of a wheelbarrow. That its recently become possible for me technologically, doesn't mean its good design or a great UI. It is in fact totally inappropriate and non-productive, although it would be an impressive hack. The analogy to the same UI on a phone and on a big screen TV is clear. On topic of computer UI, something as simple as adding multiple screens / multiple machines on the same desk dramatically changed my workflow some decades ago.
