I think the issue is “high-tech” back then was very different than high-tech today.
Back then, computers and video screens were big and bulky. Electronic devices used vacuum tubes. Devices had switches, relays etc.
Today those bulky devices are replaced by tiny microchips and touchscreens.
Consider these photos. Compare the interior of a Gemini capsule to the modern Space X Dragon.
Then look at the Kirby drawing of Doom surrounded by his bulky technology and consider how wrong that would look in a modern setting.
