Semiconductors and software have created enormous amounts of value for the companies that own them, but the Fed usually thinks in macroeconomic terms. For the macro economy, the effect of technical development on overall corporate profits is much more muted. Creative destruction destroys old industries as much as it creates new ones. For example, there's a TV show "Mad Men" about the dominance of Madison Avenue advertising firms; Google and Facebook have completely destroyed this industry. Berkshire Hathaway annual reports from the 1970s and 1980s used to say that the local newspaper for each major metro area was a natural monopoly and reliable source of corporate profits; now, this industry has been reliably commoditized by the Internet.

Of course, the creative destroyers in question would much rather focus on the "creation of value" narrative, because it avoids attracting attention (and competition or regulation) from the industries that they're about to destroy. So there are pretty significant information distortions in the popular narrative.

Interest rates and corporate taxes have the property that they affect the whole market, which makes them much more useful to the Fed. If you bought NVidia in 2022 or Apple in 1998, congrats, you made a good investing call. But if you bought the S&P 500 in 2009 and are congratulating yourself on your 600% returns over the decade, you should know that most of that is because of low interest rates, and if the low interest rate environment unwinds, so will your stock portfolio.
