In order to really make this a meaningful discussion (less the derogatory remarks towards any single profession or discipilne), I think it is helpful to go back to the beginning as to why the profession is regulated. Professional engineering is regulated, according to the statutes of my state, because the legislature deemed it necessary in the interest of public health and safety. PERIOD !!!!
In my state, "Engineering" includes the term "professional engineering" and means any service or creative work, the adequate performance of which requires engineering education, training, and experience in the application of special knowledge of the mathematical, physical, and engineering sciences to such services or creative work as consultation, investigation, evaluation, planning, and design of engineering works and systems, planning the use of land and water, teaching of the principles and methods of engineering design, engineering surveys, and the inspection of construction for the purpose of determining in general if the work is proceeding in compliance with drawings and specifications, any of which embraces such services or work, either public or private, in connection with any utilities, structures, buildings, machines, equipment, processes, work systems, projects, and industrial or consumer products or equipment of a mechanical, electrical, hydraulic, pneumatic, or thermal nature, insofar as they involve safeguarding life, health, or property; and includes such other professional services as may be necessary to the planning, progress, and completion of any engineering services. A person who practices any branch of engineering; who, by verbal claim, sign, advertisement, letterhead, or card, or in any other way, represents himself or herself to be an engineer or, through the use of some other title, implies that he or she is an engineer or that he or she is licensed under this chapter; or who holds himself or herself out as able to perform, or does perform, any engineering service or work or any other service designated by the practitioner which is recognized as engineering shall be construed to practice or offer to practice engineering within the meaning and intent of this chapter.
That is the statutory premise of establishing 'engineering' and 'professional engineering' as a profession regulated by the state.
If you go to the rules governing engineering, they provide duties that are specific to all engineers and then duties specific to disciplines of engineering, set forth as follows:
CHAPTER 61G15-30 RESPONSIBILITY RULES COMMON TO ALL ENGINEERS
CHAPTER 61G15-31 RESPONSIBILITY RULES OF PROFESSIONAL ENGINEERS CONCERNING THE DESIGN OF STRUCTURES
CHAPTER 61G15-32 RESPONSIBILITY RULES OF PROFESSIONAL ENGINEERS CONCERNING THE DESIGN OF FIRE PROTECTION SYSTEMS
CHAPTER 61G15-33 RESPONSIBILITY RULES OF PROFESSIONAL ENGINEERS CONCERNING THE DESIGN OF ELECTRICAL SYSTEMS
CHAPTER 61G15-34 MECHANICAL SYSTEMS
CHAPTER 61G15-35 RESPONSIBILITY RULES OF PROFESSIONAL ENGINEERS PROVIDING THRESHOLD BUILDING INSPECTION
CHAPTER 61G15-36 PRODUCT EVALUATION
In these cases, it has been deemed that competent individuals are responsible for the engineering work to practice within these areas because it is in the public's interest that they do so. I believe as our society expands and begins to develop more diverse needs, you may very well see the number of engineering designations expand to include those other non-traditional disciplines (e.g. software engineering) if it is deemed necessary in order to protect the public welfare.
I would gladly discuss and argue the benefits or limitations/injury this can cause to our profession. However, I urge everyone to present it within context instead of grossly mischaracterizing or marginalizing anyone's education, background, or profession.
