People in this thread seem to have different understandings of what beta software is. Strictly speaking, it's simply software that has not officially been released; however, as some beta software, including beta features in Tesla's cars, is publicly available, that blurs the distinction. Especially in those cases, there are two key distinctions between beta and final-release software; either one can make software beta:
- Known bugs -- Beta software is likely to have known bugs, or more known bugs than the publisher is comfortable with in a final release.
- Missing features -- Beta software may be missing features that the developer wants to be present in the final release version. Note that some definitions say that beta software is feature-complete, by which definition software with missing features is actually in alpha test (or earlier); however, other definitions allow for missing features in beta software.
It's pretty clear that both of these characteristics of beta software exist in some of Tesla's features, particularly Autopilot and FSD. Phantom braking, driving down the median between an exit and the highway, and other such problems are bugs; and Tesla has promised that Autopilot and FSD will do
much more than they currently do. Hence, they're beta (or even alpha, by some definitions) features.
There are several online definitions of beta software, such as
this one.
Note also that the preceding definitions were developed in the bygone era of software distribution on physical media. The pace of modern software development and distribution blurs the lines between alpha, beta, release candidate (RC), and final-release software. Decades ago, there was a clear transition from beta (or RC) to final-release software: The time when the final master was created for manufacturing and packaging into a box. Today's distribution methods, where software is downloaded from the Internet, makes such a distinction much more arbitrary. Bugs can be fixed and features added with as little or as much fanfare as desired at any point in the process. This blurs the lines between the various stages of software development to the point that they aren't nearly as meaningful as they once were. What's more, today's software is so complex that no program of any size can credibly claim to be bug-free; at best, a program might have no
known bugs, but they're almost certainly lurking beneath the surface, waiting to be discovered. Furthermore, with the exception of software that's been abandoned, features are likely to be added in the future. Thus, the characteristics distinguishing beta from final-release software aren't as useful as they once were, and the labeling becomes arbitrary.
