Can you give some historical examples of people moving the goalposts around consciousness? I agree, perhaps, for aspects of "intelligence" but I can't think of any examples of it with regard to consciousness proper.

There’s over 400 years of philosophical debate about consciousness starting with Locke, shifting with Kant, and continuing onward with real world implications throughout. By some more modern definitions an iPhone has consciousness while others explicitly exclude certain humans, and these definitions served as part of the justification of slavery and sexism, colonialism and more. I started writing an essay on this on my phone in response and I gave up there are so many examples.

To name a few you may want to investigate:

Hegel, Arthur Schopenhauer, William James, Edmund Husserl, Sigmund Freud, Thomas Nagel, Ned Block, David Chalmers, Giulio Tononi, René Descartes, Daniel Dennett, Julian Jaynes, Michael Graziano, T.H. Huxley, Otto Weininger, Simone de Beauvoir, Jean-Paul Sartre, Maurice Merleau-Ponty, John Searle, Christof Koch, Bernard Baars, Max Velmans, Victor Lamme, Stanislas Dehaene, Antonio Damasio, Anil Seth, Peter Godfrey-Smith, Galen Strawson, Philip Goff, Colin McGinn, Patricia Churchland, Paul Churchland, Frank Jackson, Jerry Fodor, John Stuart Mill, Wilhelm Wundt, Franz Brentano, Carl Jung, Jacques Lacan, Michel Foucault.
