If I was laid off by a company I wouldn’t go back unless I had no other choice. If a company didn’t see your value previously and now it supposedly does, what is to say it will not change again in the future and fire you again? A lot of companies do a last-in first-out approach and are cyclical about hiring and firing to please shareholders. That’s where these tech companies are at now.
Also who wants the potential of a CV where you were laid off twice by the same company? It’d be like them taking your CV and wiping their arse with it before handing to back to you as security escorts you out of the building.
Don’t go backwards, keep moving forward.
The BBC article that this article is a bizarre summary of is far better (the Gizmodo article even links directly to the BBC article). It give a far better overview of the issues; the main crux is they cost most than anticipated through both theft and cost of the machines themselves. The consumer’s disliking it is a less point and more naunced essentially “customer’s want the technology to work but it isn’t” which is also what you’ve said.

Personally I preferred the self checkouts because I don’t want to interact with someone, but th they fail so much (because of the weighing which is to stop me being a supposed thieving scumbag, not to benefit me) and you end up standing around waving at a random stranger to come and fix the machine awkwardly while a massive queue waits impatiently for a machine. I’ve recently switched back to the manned checkouts for bigger shopping trips.
