Labour was cheaper back then. Even valuable jobs can stop making sense if the costs outweigh them. That's the difficulty with automation making other sectors more efficient, wages get driven up while your productivity stays the same.

It still seems to me designing applications or web services is so hard that it's just easier to hire thousands of people to do customer service and having people to come physically to do things. The average corporation's business application or web page is absolutely terrible and a lot of non-technical users simply can not do business with it. Ie it is a hindrance for the businesses core reason of existence. Do the QR code things show up in revenue tracking? Do they do A/B testing? I think I prefer to choose another restaurant if I see that, or not come again.

I think some small pizza shops have had proper simple web pages, probably because it's do-or-die for them and the person contracting the web page is the person also knowing very well how the business is doing. Also phone interactions are very fast and straightforward. It's sad to see them having to struggle with terrible card payment terminals and everybody trying to take a cut (credit card and delivery companies).

True. But automation also pushes up wealth. Starbucks drivethrus aren't a thing because we need iced sweet nominally coffee stuff. It exists because we have the disposable income to pay someone else to make the coffee.

Yes a doorman is a cost, and a greater cost than previously, but we've also got more money to waste on such fripperies.
