The number isn't really the issue. The issue is that every single one is exactly the same. Skyrim had like 80? words of power but they were fun because you had to beat a boss or clear a dungeon or do a quest. In Skyrim you got at least some personal touch to getting those words.

In Starfield it's always the same 1-2 minute walk from ship to temple and then float around in a small room until the central thing opens and then you get teleported outside the temple where you kill 1 guy that 90% of the time spawns directly in front of you. If it was as many times as in Skyrim it would still be mind numbingly boring, because there's nothing interesting about them.
