Is Software development that easy?

I have observed individuals, including siblings of my peers, transitioning into software development roles. However, some face challenges in developing professional skills throughout their careers, often displaying unprofessional behavior, such as being rude to colleagues. Interestingly, a few of them do not hold formal degrees or have pursued non-technical educational backgrounds, such as a BA.

I am not opposed to individuals who demonstrate a genuine willingness to learn and grow. In fact, I am more than willing to support them. However, if someone enters the tech industry solely with the intent to earn money, without striving to be a professionally reliable and collaborative colleague, it raises serious concerns.

Is this how tech will bloom in future?
