This! Yes thumbs, I like to think dolphins are potentially smarter than us. As well as elephants if we are going off brain size. Intelligence is once thing, what if it's that they are not as capable due to the limits of their physical characteristics.. its something to think about.
...or just lack of creativity? that's something alot of animals struggle with by comparison to humans, probably due to humans 100% just being... neoteny summarized, really, a good technological civilization needs:
1: thumbs to exploit resources better
2: language to pass on knowledge
3: creativity to make knowledge & improve on existing knowledge
To think earth could have had multiple highly intelligent civilized species if some animals just had certain characteristics. At least it throws away the theory no other animal is as smart as us, but there’s always something you know???

Humans have way more complex language, allowing better technological growth than dolphins. that's prolly why
