Why is consciousness computation? What does it even mean to say something feels like being "a type of computation"? The concept of consciousness is wildly more expansive and diverse than computation, rather than the other way around. A strict materialist account or "explanation" of consciousness seems to just end up a category error. I take it as no surprise that a website devoted to the computers and software often insists that this is the only way to look at it, but there are entire philosophical movements that have developed fascinating accounts of consciousness that are far from strict materialism, nor are they "spiritual" or religious which is a common rejoinder by materialists, an example is the implications of Ludwig Wittgenstein's work from Philosophical Investigations and his analysis of language. And even in neuroscience there is far from complete agreement on the topic at all.
