One thing the parent's post suggests, though, is that we do have better standardization and interoperability. Data normalization is a problem that has largely been solved. So is reading and writing data at scale. Once you've gone to SQL, you presumably won't ever need to go to some other database language or drastically restructure your data in order to rewrite your backend or frontend next time. Similarly, there aren't fifty different schemes for serializing data anymore. JSON is "good enough", every language can now parse it and probably will for the next hundred years. So parts have become more interchangeable. The burden on experienced programmers is less, and it's easier for novice programmers with a shallower base of knowledge to work on pieces of a project even if they don't understand the whole thing. In this sense, tech has become less of a moving target.
