We have had some recent changes to the end dates for existing technology previews. So I figured it was time to repost an updated version of my milk carton blog article.

Most technology previews are like milk cartons. They have expiration dates on them. When a technology preview expires, the technology preview no longer operates. A preview has a time-bomb in it that makes it stop working on a particular date. We do this so there is a sense of urgency to try a technology preview and get back to us. Our customers are busy people, and without this, they would just say "I'll get to that later." When a technology preview expires, any data that has been created by it continues to be valid. It's just that the data cannot be edited using the technology preview since the preview does not run anymore. Certainly new data can't be created either. This time-based approach allows us to get timely feedback, early in the technology life cycle, on the general idea, user interface, performance characteristics, and correctness of the results.

Here is a list of active Autodesk Labs technology previews and their associated expiration dates. The list is sorted by expiration date - so act fast if you want to provide feedback on these technology previews before they retire or graduate.

Technology previews have a specific end date so no one confuses them with perpetual functionality that is associated with a product offering or subscription service. In fact, technology previews are offered for free to Subscription, non-Subscription, and educational customers alike. A development team is focused on a technology preview for a project interval. While they are, they want the feedback and the ability to make a decision so they can continue development of the technology or quickly move on to something else. We appreciate it when we debut technology previews, people try them right away, and they provide us with an up or down vote. Your experience shapes the future of our technology indeed. As I always say, "Trying a technology preview, liking it, but not telling us, is the same as not trying it."

Still sniffing the cartons to see what can still be tasted is alive in the lab.
