Talking about Portenta, to be fair, Massimo and Arduino people IMO have done a pretty good job at characterising the product as "useful for something not extremely complex under the control/automation/engineering requirements PoV but where expanded IoT possibilities can be a huge selling point, and especially useful for systems which are serially produced". So, no process control or huge machinery, think more like mid-size ovens [https://www.arduino.cc/pro/case-studies-rinaldi-ovens] or things like this. I think the Arduino people are being very aware of the industry needs and are not being unrealistic "wahh PLCs sux lets throw them all away" kind of people ( :D ).
As for me, as an industrial controls professional, I welcome these new solutions, they're another tool in my toolbox. It's up to my engineering decision to evaluate the proper usage of tools.
