For a few years at least, I saw parallels between the tech industry and the railroads in the USA. Mainly tech is too big and its markets are fully saturated. The same thing happened in the US rail industry even before cars and trucks were a significant competitor. Rail lines were overbuilt even before 1893. The rail industry underwent a period of consolidation then decline. The number of people employed by railroads was once in the millions, now it's about 83,000.
Lots of people imagine that the tech industry is laying people off because of "AI". I think in a way that's true. The "AI" portion of the tech sector is currently absorbing lots of investor cash and turning it into hardware and data centers so there's not as much investor money for other schemes.
Many of the new areas of tech are speculative and implausible sci-fi stories and are really just schemes to sell stock. Even worse, many new areas in tech are part of the gross technocratic surveillance corporate/government hybrid monstrosity.
Anyway, I'm currently on my final tech job. I'm not sure how much longer it will last. I'm looking forward to moving onto the next thing, whatever it might be.
