The core of our business has changed. Fewer users are developing their own test applications; instead, they're buying something off the shelf like TestStand. Fewer users are developing their own data acquisition software; instead, they're buying something off the shelf like FlexLogger. This trend alters significantly the role of LabVIEW (CG and NXG) in the NI ecosystem -- it becomes far less important to support whole application development (though, of course, we still do and will) and far more important to support "just a bit of customization" when the pre-built tools fail. A lot of software has an endless array of switches and options, but LV provides the ability for a user to write a custom routine to specify the behavior they want in some corner niche of a product. Think like Signal Express, able to generate sine wave, square wave, triangle wave or "pick a VI that generates the wave that you need" wave.
What's funny about this is that although the app devs are growing rarer, they're also individually growing more profitable for NI as a whole because the companies still paying to develop custom software are the ones that are generally buying a lot of hardware to do something unique in the world (or not in the world, in the case of SpaceX, Blue Origin, Ad Astra, etc.). So I don't expect the big scale parts of LabVIEW to vanish, but I do expect them to be driven by specific requests from megascale customers rather than from the massed collective. The massed collective will be driving more of the IDE developments. At least, that's my suspicion at this time based on the presentations I've seen.
