I strongly believe that step 1 is sufficient or almost sufficient for step 2, i.e., that it’s impossible to give an adequate account of human phenomenology without figuring out most of the computational aspects of consciousness.
Apologies for nitpicking, but your strong belief that step 1 is (almost) sufficient for step 2 would be more faithfully re-phrased as: it will (probably) be possible/easy to give an adequate account of human phenomenology by figuring out most of the computational aspects of consciousness. The way you phrased it (viz., “impossible...without”) is equivalent to saying that step 1 is necessary for step 2, an importantly different claim (on this phrasing, something besides the computational aspects may be required). Of course, you may think it is both necessary and sufficient, I’m just pointing out the distinction.
Mhh, I think “it’s not possible to solve (1) without also solving (2)” is equivalent to “every solution to (1) also solves (2)”, which is equivalent to “(1) is sufficient for (2)”. I did take some liberty in rephrasing step (2) from “figure out what consciousness is” to “figure out its computational implementation”.
