procedural diagnostics - basically "expert systems" that any intelligent person could use to repair complex machines or human bodies

GE built one of the first expert systems for locomotive repair, which combines all existing knowledge derived from the collective years of experience of locomotive mechanics.

Probably called "AI" now.

In order to secure a monopoly control of healthcare the cult created the AMA.

AMA kept out rival con men, including the biggest of all time, the infamous goat gland doctor Brinkley of Kansas who promised to restore the rickety rich old rancher to full sexual powers.

Doc Brinkley was doing nearly a million some years – at the height of the depression. Many suspiciously shill patients swore to their transformation - often sporting teenaged wives.

In reality his patients who survived the infection and rejection of implanted animal testes were impotent cripples for the rest of their lives.

The AMA couldn't have found a better straw man to tilt at - which suggests they may have created Brinkley to get the AMA monopoly past a public skeptical of trusts, monopolies and the philanthropy of the rich in general.

When the first head of the AMA (with Mencken's help) drove the dirty doc out of Kansas he moved his clinic just across the border from Laredo, and built the first 50,000 watt AM border radio to shill his surgery all the way to the Canadian border. The dick chopping Doc employed teenage Willie Nelson to croon to the love lorn between add for miraculous goat gland surgery.
