Reposting and Tesler’s Legacy

  • Several note this is an old article resurfacing; some see “inventor of cut/paste” as reductive.
  • Others argue that focusing on cut/paste is effective for lay audiences and conveys how early and influential his work was.
  • Some point out that he also helped coin or popularize terms like WYSIWYG, “browser,” and “user friendly,” and pushed modeless, user-centered design.

Cut/Copy/Paste: Invention vs. Adaptation

  • Multiple comments stress “cut and paste” existed as a physical publishing process long before computers.
  • Early editors (TECO, etc.) already had similar operations; Tesler is framed more as adapting and naming the concept for GUIs.
  • A key contribution highlighted is the selection model: cursor as “between characters,” selection as a range, and unified replace/insert behavior.
  • Some dislike that cut/paste introduces “hidden state” (clipboard) and prefer select-and-move or X11-style primary selection.

Modes and Interaction Philosophy

  • Tesler’s “no modes” principle is widely cited as influential; some see cut/paste as in tension with it.
  • Others note that modern tools (e.g., modal editors like Vim, car “eco/sport” modes) show modes can be powerful but must be used sparingly.

One-Button Mouse Debate

  • Strong disagreement: some call it one of the worst ideas, arguing at least two or three buttons are needed and double-click is undiscoverable and confusing.
  • Others defend it as the right choice for 1980s novices, reducing complexity vs. multi-button PARC mice with inconsistent semantics.
  • There is discussion of keyboard modifiers effectively giving the Mac “virtual” extra buttons.

WYSIWYG vs. Markup

  • Some argue WYSIWYG was revolutionary for its time, democratizing desktop publishing.
  • Others think it was a bad long-term idea: encourages ad‑hoc visual poking instead of structured document semantics, causing fragile layouts.
  • Alternatives mentioned: print preview, TeX/Markdown flows, “reveal codes,” and human-readable markup generated from visual tools.

Broader UX Themes

  • Multiple commenters lament modern regressions: inconsistent mobile UIs, loss of tooltips/manuals, touch paradigms leaking into desktop.
  • Amazon’s interface is criticized as cluttered and confusing; anecdotes suggest internal resistance to redesign, possibly for business reasons.

Other Contributions and Concepts

  • The ARM/Newton investment is noted as indirectly crucial to Apple’s survival.
  • Tesler’s Law (conservation of complexity) is referenced as a useful mental model: complexity can be shifted but not eliminated.
