Not sure if these are hot takes:
I agree with your first point, but pretty strongly disagree with the other two. Code review is critical. Devs should be discussing changes and design choices. One Dev can not be all things all the time and other people have experience you do not or can remind you of things you forgot. Programming language absolutely matters when you’re not the only dev on the team.
If code reviews in your org are glorified "styleguide checks", then they are not really code reviews at all.
Also, if you're only getting design input at code review time, that's WWAAYY too late in the process.
Code reviews should be:
Establishing that the code has proper test coverage (functional correctness VIA coverage, not code observation)
Establishing that it doesn't have unintended consequences in the ** implementation** (making db calls in a loop, exposing secure information, etc)
That the implementation is of the high-level design that was already established and agreed upon by the larger development unit.
A opportunity to ask questions to learn from whoever wrote the code
An opportunity for the reviewers to teach techniques that could have helped in the code
