[MCU] Mind uploading in Captain America: The Winter Soldier, how did it happen?

How did biochemist Arnim Zola managed to upload his mind/consciousness into a computer and managed to survive without someone controlling the keyboard? And how is he still receptive and responsive after all these years? Is that count as immortality?

Hydra and SHIELD are far more advanced than the rest of the world's technology. He uploaded his mind in the early 1970s into a supercomputer, far more advanced than any other computer of the era. Being a Hydra biochemist, mind uploading is entirely within his and his colleagues realm of possibility. It's a quite durable computer but it wouldn't last forever. As shown when Captain America punches out the monitor, he has full control over the computer from the inside so he won't need outside help from a keyboard.
