I would argue that the "Golden Age of Programming" came about due to the existence of Javascript and the ubiquity of the web, introducing the masses to a simple, easy to use development and distribution environment. Also that brief time when free web hosts like Tripod offered CGI access and scripting.
The rise and fall of programming as a job in Silicon Valley is a separate but related phenomenon. A gold rush, but not a golden age.
To that end, when corporate interests commoditized the web and everything became too complex and javascript got treated as bytecode and required a package manager and toolchain, the golden age was absolutely killed by big tech.
