At the height of the Cold War, one very specialized computer was so secret that the world didn’t know it existed. It ran its jobs up to 200 times as fast as any other computer of its time. It was the U.S. National Security Agency’s main cryptographic processor in operation from the time of the Cuban Missile Crisis in 1962 through the Vietnam War and on past the 1975 Helsinki Accords. The machine stopped running only when its moving parts finally gave out.The Harvest computer mattered because of what it was as well as when it ran. For 14 years, it was the engine processing the NSA’s most sensitive intercepts at a time when signals intelligence was as close to a strategic weapon as anything short of a warhead.Designed and built by IBM for the NSA, Harvest was one of the first machines designed to apply operations to enormous datasets rushing past, a precursor to the computers today that manage continuous video streams and security systems in real time. It was also one of the first machines built as an add-on—a specialized helper intended to do one job exceptionally well, bolted onto a general computer. Harvest’s modular design is like a 1960s version of today’s graphics chips that CPUs use to run intensive video-game and AI processing loads.All that raw processing power meant that Harvest also needed nonstop rivers of data to run on. And that led to another pioneering achievement: the world’s first automated tape library that could robotically fetch any one of hundreds of large cassettes of magnetic tape from the machine’s racks.Given Harvest’s unprecedented processing and storage capacity, the machine’s designers naturally needed to rethink how their system handled information. So IBM wrote a customized programming language called Alpha to let code breakers rigorously describe cryptographic problems, just as scientists at the time were using the emerging language Fortran to describe equations and data-processing algorithms.

This article is brought to you by Ollobot.From about 2017, individuals began to truly connect with the initial wave of companion robots. These devices had personality, moved around, joked, and answered when you spoke to them. Most early companion robots, however, were still limited by simple voice-command interactions and narrow functionality. Once the novelty wore off, many ended up sitting unused on shelves. As some of those companies went out of business and turned off their servers, many owners likened it to losing a pet.What Ollobot describes as “gentle intelligence” is a useful way to think about where the serious work in this category is going. Not toward more powerful assistants, but toward more present ones.The problem companion robots were trying to solveLoneliness is not a niche issue. According to one study, nearly one out of three elderly adults resides alone, meaning they do not have daily companions. Research also shows that children whose parents have migrated for work, leaving them in the care of relatives, were 2.5 times more likely to experience loneliness than children whose parents remain with them. Among working adults living alone in urban environments, similar patterns of social isolation emerge, even if they are less visible.Over the years, technology has time and again attempted to solve this problem via video calls, smart speakers, and messaging apps without much success. Those tools are geared towards communication between people that already have relationships. They do not create presence. They schedule it. That is the gap that a new generation of AI companion robots is being engineered to fill.Today’s AI robots are differentToday’s companion robots are not just cute and cuddly. They are designed with psychological research, clinical insight and long-term interaction models to be truly useful in real homes.Three fundamental shifts define the current generation:From reactive to proactive response. Older robots relied on you speaking to th
