That's the problem: in the current design of Emacs and Elisp, we can
and do share data between buffers.

In the web-browser, each "tab" is its own virtual-machine, with very
little communication between them and very little sharing.

In Emacs, on the contrary all the functions and the global data defined
by the loaded packages are shared, and additionally to that some of the
buffer-local data is also shared.
