My first exposure to intelligent design detection in science took place during a summer job with National Defence Research in 1978 as an engineering student.
What is it, metaphysically one might say, that distinguishes design in the ID sense from ubiquitous teleological design, in a Thomistic sense?
“Technosignatures” is just abstruse enough to evade most Congressional waste hunters.
This is one key issue on which proponents of ID and of theistic evolution differ.
Some scientists may denounce ID as a movement, but they find its practice very useful.
