In terms of actually building something close to the completeness of an Iron Man suit? No.
A) We don’t have powerful / dense enough energy sources. Ironman is powered by a fictional Arc reactor because we have no power source that small that can produce that much power.
B) We don’t have any quiet forms of airborne propulsion. You kind of hear Ironman’s jets sometimes, but not really, and in reality all our jets / fans that can produce enough thrust to lift a person are way louder.
C) Any material strong enough to actually be protective and stop bullets will also way a ton, making flight even more difficult.
D) In reality an Ironman suit wouldn’t be able to stop you from killing yourself through concussions whenever you crashed or hit anything.
not an expert, but the fictional part isn’t the suit, it’s the miniaturized high energy production courtesy of stark building it in a cave from scraps.
we have mech suits. we have flight helmets with sophisticated Ai and we have privatized versions of personal assistants.
Closer than what? In the past? Yes, of course. We’ll always be closer, unless there is some cataclysmic event that causes us to lose knowledge and regress.
