Technologically, that's probably not true. Thatcher, for example raised alarms in the political/public sphere based on advice from government scientists in the late '80's IIRC. A lot could have been done in the last 30 years.
Politically/sociologically though, you're probably right. Views on economic growth, the nature of the good life for humans, the relationship between the real ('nature') and virtual ('economy') worlds, public and private goods, etc, had all become sclerotic & fixed as invisible myths by that time.
