So I understand you experienced difficulties in dealing with developing intelligences, and you entailed that it should be difficult to create artificial ones.

So I understand you experienced difficulties in dealing with developing intelligences, and you entailed that it should be difficult to create artificial ones. But nobody said it was easy (also because ideas like "to invent the lightbulb is not easy" in that form make little sense), and yet the "right" people - not "«we»" - will probably reach the goal, partially owing to a piece of the "«we»" and largely in spite of a large piece of the "«we»". Just like some achieved the lightbulb, and some (Columbus) achieved making an egg stand straight on the table while those nearby claimed it was impossible. Now, the problem in the original context was not about those people able to create a hammer, but about the people unable to use it. The problem here is not about creating intelligence but using it.
