> Achieving goals? Why not define it as making predictions?
Because "achieving goals" subsumes "making predictions". Remember, Russell's goal is to find a definition of intelligence that is broader than humans -- and even broader than sentient beings. But using the "achieving goals" definition, one can include system that accomplishes goals, even if we can't find any way to verify it is making predictions. For example, even a purely reactive agent (e.g. operating on instincts) can display intelligent behavior if its actions serve its purposes.
If you are seeking one clear point of view about the nature of intelligence, I highly recommend Russell's writing. You don't have to "agree" with his definition, especially not at first, but if you give it a fair reading, you'll probably find it to be coherent and useful for the purposes he layes out.
Russell has been thinking about and teaching these topics for probably 40+ years in depth. So it is sensible to give his ideas serious consideration. Also, there are scholars who disagree with Russell's definition or accentuate different aspects. Wherever a person lands, these various scholars provide a clear foundation that is all too often lacking in everyday conversation.
