Who is a professional?

Question

IT education

Hello
In the process of listening to various speeches on professional development and reading questions on the Toaster, the question arose - 'Who is a professional?' and from this came another question - 'What do they pay a lot of money to a professional?'
Who determines whether a person is a professional in his profession or not?
Professional == the responsibility that a person takes on?
This leads to another question
. Is the one who, let's say, has a large amount of superficial knowledge of various technologies in different languages ​​​​(or just has an idea), but takes responsibility, is a professional?
Is the one who knows his direction very well (language, frameworks experience)
but does not want to take responsibility, a professional?
Are the definitions of 'Junior' , 'Middle' , 'Senior' objective or is it all subjective?
UPD 1 Do I understand correctly that a professional can be compared with an independent business? But still, who determines whether a person is a professional or not?

Answer 1

In Russian, this word has 2 meanings - and these meanings are often confused:
1. The one who makes money with this. Without regard to the quality of his work.
2. The one who solves the problem. One who has a professional qualification.
The borders of jun, middle, senior are conditional, not formal.
But, if we are not talking about a specific person, but on average about everyone, they are quite objective.

Answer 2

A professional is someone who turned a hobby into a profession =)

Answer 3

Answer 4

It seems to me that a professional is a person who can formulate, launch, release a product. A professional not only has rich experience in his field, but can also sell ideas to an interested person and get approval for implementation where everyone will be sure that he will be able to correctly distribute tasks and successfully deliver projects one by one. People in positions of leadership are paid money for the fact that they know how to lead! Although many people forget this, we do not take passengers into this calculation, these are side chelas who, in good times, are not bad for the company ... well, they are doing something, we need to consult.
Are the definitions of 'Junior' , 'Middle' , 'Senior' objective or is it all subjective?
Not knowing how they differ from each other - yes. Many people think
What do they pay a taxi driver, a plumber, a builder? That's right, for solving your problems.

Answer 5

The professional has extensive successful experience in a particular area, is able to solve the tasks and problems of the employer without failure. And responsibility is an accompanying matter that goes without saying.

Answer 6

A good question, for me a professional is someone who is not afraid to take on any responsibility and bring the work they have started to great results.
