Making non-trivial things work in Scratch can be fun for similar reasons that it's fun to develop games for the NES in 2025, using modern tooling [0].
NES development would be easier if you upgraded the hardware to be more capable, but that would defeat the purpose. It could still be an interesting project in its own right, but it's not "solving" the same problem.
With Scratch, there are also fundamental practical limitations. Dragging stuff around with a mouse becomes a chore, once your code passes a modest size. Maybe you could invent a system of keyboard shortcuts, but that sounds even harder to use.
We already have mountains of excellent tools for working with text, from IDEs to git forges. It'd be really hard to build something competitive, for scratch blocks, from scratch.
Agreed.
Existing tooling is literally the only reason why.
But there is nothing inherently better about text.
