Physical products are hard. Automating them means you've screwed up half a million times and have a lot of cash to even do it.
(Perhaps a business case of “on-shoring makes sense if everything is automated!” that failed to account for the challenges of opening a fully-automated facility)
Now get this, someone could say "we're going to do it with AI from day one!" Blow 40million, to contractors because ew who wants to own their production, and fail. Black box technologies and contractors have different risks entirely.
There's a lot of reasons why attempting to revive thirty year old practices to still be profitable is more than a challenge. Hence why they failed.
The explanations make no sense in the article. Automating heat treatment is computationally expensive? What the hell are they talking about? The guy who is doing the heat treatment is not doing computation!
Wait I guess I do buy it...
