"He is not finding the answers" vs "He has not found the answers"

Example (1) is a line from a TV show/movie. I’d like to know what the difference in meaning is between (1) and (2):

(1) [It (i.e. Peter’s attic workroom) is filled with electronic equipment. Camera pans to Peter at a desk which is piled high with books. Camera moves in close to show they are books on physiology and biology. Peter is intent on them but] he [b]is not finding[/b] the answers to his strange, new prowess. (Scenario in [i]Spider-Man: The Mind Stealers[/i])
(2) ...but he [b]has not found[/b] the answers to his strange, new prowess.

Not finding is present continuous it means in the present going into the future

Has not found is past perfect, a completed action in the past.

The difference is meaning has shades of difference in the exact time and continuity of the actions. If you aren’t specifically interested in the exactness of the time frame of the actions either may be used.
