When he mentions the lack of cables, he's pretty close with most of them being underground. But also he's incredible close if you consider the mess of cables that was the Stockholm telephone tower, functioning until 1913 https://www.amusingplanet.com/2017/09/the-stockholm-telephon...
It is an excellent article, I agree. However, it strikes me that the author was more likely female than male. (gender deliberately obscured in the author's name, 'W.L. George', for instance.).
If a male writer, the article is even more impressive given the clear sensitivity to, and awareness of, women's issues and the likely impact of technology and social changes on women.
That said, the author was likely a person of privilege rather than someone more representative of the population of 1922. A starving writer was unlikely to have been so focused on the challenges of hiring good household staff.
But it is unlikely that women will have an achieved equality with men. Cautious feminists such as myself realize that things go slowly and that a brief hundred years will not wipe out the effects on women of 30,000 years of slavery.
Cool! Excellent predictions for the future, not just for technology, but also for social change from a broader perspective than just that of the lived experience of the author.
(W.L. = Walter Lionel, as revealled by a bit more searching)
