Human Evolution if Dinosaurs never died off
Assuming there were no extinction level threats to the dinosaurs, and they never fully died off (and survived the following ice ages), how would this affect the evolution and technology use of humans if at all?
Given that a T-rex is about the same size and speed as an elephant, and velociraptors are slightly faster than wolves and slower than lions, I presume that we would just handle these dangerous creatures much the same as we handle similar and the major difference would be in fauna and flora.
My question is not how would we survive with them as Could humans survive with dinosaurs? answers, but specifically how them surviving would affect our evolution and technology development.
The linked question specifically states "Okay, quite a few people have asked what technological level the humans are at. Well these humans were on a generation ship before so I would assume space age level." Where i am asking if humans could develop and if so how would their tech change if at all to deal with these creatures.
Very specifically, the other question asks if a pre-existing human civilization could survive if introduced in an environment where Dinosaurs still roamed the Earth. This question is asking if humans could still EVOLVE on such a planet, and if so, what major biological and psychological differences might there be on such a planet.

Assuming that the dinosaurs survived, and somehow humans also evolved to what be what they are now, so dinosaurs exist alongside humans, humans would have hunted most of them to extinction, or at least submission.
Humans don't do well at tolerating animals that threaten humans. Most dinosaurs that live in areas that humans want to live would be killed, domesticated, or driven off.
There would still be dinosaurs in places that humans don't really want to live, such as jungles, savanas, wilderness, etc. which are the same places that the big predators live now.
Things like lions, tigers, and bears live in these places mostly by leaving humans alone. Humans still go into those places to hunt the animals though, so they wouldn't be completely safe.
