LINX now is supported on commercial applications starting in 2020 BTW.
Your opinion is valid, and you have reasons for it, but I think it might be a bit of forest from the trees situation here. LabVIEW tends to have a one or two major bullet points of new features with each release, with many smaller improvements that are less noteworthy. Some of these aren't very applicable to me and I don't see the benefit of the update, but I can still recognize that a bunch of effort was put into a making it into the release, and makes me think NI isn't sitting idle. I know I made a list like this in the past when a similar topic has come up but I'm having a hard time finding it.
2012 - Loop Tunnel improvements with concatenating, conditional, indexing, and last value / Project Templates
2013 - Improved Web Services / WebDav / SMTP / Bookmark Manager
2014 - Actor Framework (I might be off by a version or two) / 64 bit Mac and Linux support
2015 - Custom Right Click Framework
2016 - Channel Wires
2017 - VIMs / Forward Compatible Runtime
2018 - Command Line Interface / Python integration / Type Specialized Structure for Improved VIMs
2019 - Sets and Maps
2020 - Interfaces for classes / Free Community Edition with Application Builder
And here are a few of my favorite features that I can't remember what version they were added. Error Ring, Improved VI calling under Application Control for starting asynchronous processes and static VI references, DVRs, Conditional Disables based on environment or Project variables, Linux Real-time operating system, allowing for 3rd party and open source tools to be installed and called with the System Exec, and then adding an embedded HMI, User Events, LINX toolkit for running LabVIEW VIs natively on a Raspberry Pi, or controlling an Arduino connected to the host, QuickDrop's plugin system allowing for all kinds of tools, filtering on search results, improved performance of tree and listbox controls, NIPM, and loads or more scripting functions with more added with each version.
I sure hope LabVIEW has a future because I've hitched my career to it. But even if NI closed its doors tomorrow I feel like I'd still be using it for another 10 years or so, or until it didn't run on any supported version of Windows. But I feel your concern, and if I were a junior engineer starting out, I would feel safer in another language.
