In the early days of digital communication, IRC (Internet Relay Chat) was the go-to platform for real-time conversations. Launched in 1988, it provided a simple way to communicate in groups or directly with other users. But as technology evolved, so did the demands and expectations for communication tools. Today, we see a plethora of options like Slack, Discord, and Microsoft Teams dominating the landscape. So why isn’t IRC keeping up, and what exactly is holding it back?
One major limitation of IRC is the lack of server-side message history. LorenDB aptly pointed out that Matrix, a modern alternative, includes functionalities like end-to-end encryption (E2EE) and persistent message history out-of-the-box, making it a more robust option for contemporary needs. Unlike IRC, Matrix doesn’t require custom extensions to fill these gaps, making it a seamless choice for many. The absence of message history in IRC is a significant drawback, especially for companies that need a record of conversations for compliance reasons.
However, the old-school charm of IRC’s transient nature is not lost on everyone. Skilled makes a compelling argument that shell sessions and bouncers can alleviate this history issue for those who really need it. There is a sense of magic in the fact that IRC doesn’t clog up with historical data, allowing conversations to be as ephemeral as face-to-face meetings. Yet this flexibility is often more of a hindrance than a help; not everyone, especially non-tech-savvy users, can manage or appreciate this idiosyncratic feature.
Moreover, one cannot overlook the challenges in user experience (UX) and user interface (UI). As several comments suggested, the UX/UI of IRC is practically ancient compared to modern apps. Tools like Slack offer intuitive, aesthetically pleasing interfaces that require minimal setup. As doubled112 succinctly put it, you can’t just instruct Julie in HR to set up a persistent shell session and a bouncer. Modern tools simplify onboarding to the point where users just have to login, often through something as simple as an OAuth or Single Sign-On (SSO) provider. This convenience is invaluable, particularly in a corporate environment where time is money.
Persistent history extends beyond just retaining messages. It’s integral for search functionality, onboarding new employees, and overall organizational memory. Skilled makes an interesting point that integrating IRC servers into a user-friendly front-end like The Lounge can approximate some benefits of modern chat apps. However, the cost and maintenance associated with such setups—building custom extensions, ensuring they work seamlessly, and maintaining them—often outweigh the benefits. WJW likened this to the analogy of open protocols like IPv4 and IPv6; it’s difficult to get everyone on board with new features collectively.
Adding to the complexity is the need for modern integrations and compliance with enterprise standards. As elric and ebiester highlighted, critical functionalities like file attachments, user authentication, and retention policies for message history are intrinsic in modern chat apps. Slack, for example, allows administrators to move messages easily between channels, enforce retention policies, and integrate with numerous other services. The practicality of such solutions, despite their costs, generally outshines IRC’s DIY nature.
As saghm sums it up, rolling your own IRC-based solution or even an entirely new protocol comes with both financial and operational risks. While IRC remains a valuable tool for certain technical communities and niche uses, its ability to scale and meet the demanding requirements of modern enterprise communications is highly limited. The modern messaging landscape demands ease of use, robust features, and seamless integrations, areas where IRC, despite its rich history, significantly lags.
