You are welcome to pose a definition of technologist that included the people you mean to include and excluded the people you mean to exclude, but by any coherent definition doctors are as much technologists as IT workers in general, though I can see some reasonable definitions that would exclude most of both and only include a few of either.

But, in any case, the lack of formal ethical rules applicable to IT is not about how necessary technologists are or aren't compared to doctors.

Just Google it, I don't need to propose anything.

Neither of the two definitions at your link seems to serve your "include IT, exclude medical doctors" purpose.

Doctors are neither experts in a field of technology nor are they paid to operate technology.
