The key is that if it requires some sort of certification, as Canada claims it does, then it should be a modifier/adjective on the title like "certified janitor" or "licensed engineer".
Just claiming an existing single common noun as an exclusive term belonging to your organization is clearly an untenable position. If you have to keep reminding everyone that they're infringing on your trademark all the time by using a common word, you've already lost.
only if they are to be prosecuted in case of toilet malfunction!
A long time ago in Paris the street sweepers were euphemistically called "surface engineering technicians" (paraphrasing from the French "technicien de surface", but I think this is close enough)...
Take away the software, and how do the professional engineers work? No CAD. No structural analysis. No fluid dynamics simulations.
I think that's a bit harder to replace than it is to clean a dirty toilet. Presumably the professional engineers can clean their own toilet if absolutely necessary.
>Is engineering the same now as it was before software?
The core concepts which make engineering engineering? Yeah.
>The group that wants to protect or maintain ownership of the word "engineer" is dependent upon the people whom it objects to also using that title.
They are as dependent on software as any other institution, on a day-to-day basis, which have transitioned to computerized automation over the last ~60 years. Software aids efficiency.
The argument that engineers are incapable of designing and constructing sound solutions without software is unsound.
