You underestimate how important hands are to the human dominance. Cephalopods have tentacles, and 8 of them. That's the only thing even slightly comparable to hands. Beaks and bird feet developing industry? Not happening.
While dolphins and crows are as intelligent as your average American, they simply lack the means to manipulate the world in a way that leads to technological development.
How certain are you that you're not actually in Florida?
They wish. They aren't building shit with those flippers. It's absolutely the cephalopods next. Dolphins might be like the horses to the octopus.
Now I want to make this. A brain made of ribbons of strawberry ice cream, with a thread of sour lemon in the middle and tiny pop rock neurons.
Don't waste food.
If a recipe calls for four cloves, say fuck it and bang in a whole head. Cuz garlics fucking good for ya.
Oh shoot, you're right.
When data gets the emotion chip and tries drinking. "I hate this", takes another sip, "oh yes! I hate this! This is revolting!".
Chess takes lots of time to get very good. Any actual scientist, professor or engineer doesn't have the time.
Even Bob still rents though.
You fundamentaly misunderstand evolution if you think a bird wing would evolve into a hand.
You're thinking about it like intelligent design. This would be a good idea, so it will surely happen.
Evolution requires many generations of slight variations each being slightly beneficial over the last.
Crows would sooner develop hand like feet than lose their wings.
Edit:
Also, we're talking about mining? Let's put a crow wing and octopus tentacle in an arm wrestling match. The octopus crushes the whole crow, bones and all, with one tentacle. It's not even close. Birds are fucking fragile.
