Bostrom is assuming there's a thing called "computation" which is somehow a fully-specified solved problem. (It isn't).
Worse, he's also assuming that this "computation" can somehow simulate something called "consciousness" - which unfortunately for him, is nowhere near to having the formal rigorous definition that "computation" as we know it today would require.
And finally after all that, you get something which is subjectively indistinguishable from life itself.
Well - obviously. If you don't define any of your terms and assume your argument is correct because you don't show your working or get into specifics, you can argue whatever you like.
