Although this is a bad take overall, there is some truth to the idea that tech skills become obsolete faster than skills practiced in other areas of the market, and likewise tech assets become obsolete faster than a lot of physical assets. People construct buildings to last for a hundred years or more, but a lot of developers assume that within 10 years, most of the stuff they're building now will have to be re-built with more up-to-date technology. But that is simply a result of a high-growth segment of the market. It doesn't mean that software engineers are any less valuable. It simply means that in order to continue to remain in the business, they need to be able to adapt to frequent changes.
