[Iron Man] How close are we to actually possessing the technology Tony Stark uses in Iron Man?

I'm talking about hologram displays, smart AI/voice recognition, etc, NOT the Iron Man suit technology.

Hologram displays are in use if you've seen the news. However, they aren't very common and are exorbitantly expensive to use.

*Note: Hologram interfaces are only good if they are being used in the same manner as which Stark uses them in the movies i.e. large tables for standing a round and interacting with in a creative manner. Actual holographic interfaces in a computer (Like in Mass Effect) would be painful to use as it puts a lot of strain on your wrists and arms and would put you at greater risk for arthritis.*

Smart AI are really far off. At least fifty years at the minimum. More likely to be over one hundred years.

The Arc Reactor is effectively a miniature fusion device. Not happening for at least 50 years.

Exoskeletons and such are still in development but may see use in the decade or so. Robotics technology advances at an extremely fast rate.

The automated drones that Vanko used in Iron Man 2 are technically possible but would require an adaptive AI which may exist in twenty years or so. If it was coupled with a human operator, more likely ten.
