Science Quote by Stephen Wolfram

Compatibility is the least sexy kind of genius, and Wolfram is selling it like a feature and a philosophy. The line opens with a disarming bit of managerial plain-speak ("Well, the first thing to say..."), but the real message is: trust the platform. In software, especially in scientific computing, the deepest fear isn’t that a new version lacks a flashy tool; it’s that it breaks your lab’s fragile, years-long accumulation of scripts, notebooks, and institutional habit. Wolfram is targeting that anxiety directly.

The intent is practical PR, but the subtext is empire-building. By promising that "any program" runs "without change", Wolfram frames Mathematica not as a product you buy, but as an environment you inhabit. Backward compatibility is a kind of social contract: you invest your time and intellectual capital here, and we won’t punish you for it later. That’s how platforms lock in communities without sounding coercive. It’s also a quiet flex of engineering authority: maintaining compatibility across versions is hard, and saying it out loud implies a disciplined architecture and a long horizon.

Context matters: Mathematica 3.0 arrived in an era when scientific software was proliferating, standards were messy, and researchers couldn’t afford rewrites every release cycle. The mention of notebooks is key, too. Notebooks aren’t just files; they’re a hybrid of code, narrative, and results - a record of thinking. Ensuring they can be "converted" is a promise to preserve not just computation, but memory.
