Our company developed for twincat3. Yes there is progress. And yes it is very slow.
None the less - the inheritance & interfaces work. And the community produces great stuff - low and behold. A wild UnitTest framework for PLCs appears.

...and nobody will follow their lead [as quickly as you comment seems to suggest].
I've just come out from a discussion with a customer (young guy, circa 30, not a "boomer"), head of a major wastewater treatment plant in my circa 4 million ppl. metro area...he doesn't trust software, he would rather put relays everywhere and go on like that.
The problem is not only the velocity of those who produce the systems, it is also the mentality at the end users' side.
This is why I say that the transition will be slower than it could be; there are so many parts involved.
If it only were a problem of "rate of innovation produced per unit of time" I would 100% agree with you (and not only 50% as I do :-) )
(BTW, any industrial automation person living in Northern Italy: be wary when working for the company whose name is like "ZIP code" in Italian, there is lots of work to do there, but the technical org is suuuuuch a mess)

Im not pessimistic. Im just realistic. This is not enough speed to keep up with something disruptive brewed within AMZ or TESLA.
