I've been working professionally for 25+ years depending on when "professionally" starts and almost _never_ has been "the team can't build it" even in the context of companies that are basically mountains of mediocrity. The problem has _always_ been that the team didn't know what to build, and very occasionally, the best way to build it for the long term.
The difference is stark even at large companies. Oncall shifts for friends at places like Amazon and Meta are nightmares of constant pages and stress. Oncall shifts for my friends at Google have tended to be far lower key, with dramatically fewer pages and more straightforward resolutions when issues appear.
That Amazon and Meta are worse than google, well, I will grant that. Meta's internal culture is crazy.
Google’s problem was never a lack of ability to build and run impressive engineering artifacts. It was always that the business and product side of things was run very poorly.
