Future of ServiceNow developer

Hi community.

I am a SNOW developer with about 1.2 years of experience. I want to know if this is a good/okay tech stack or not. Are there enough demand for SNOW developers or is it better to work on other skills? I have a total of 2 years experience and sometimes I feel I am not doing anything at work. I feel like anyone could do what I do and it's a mistake to stay in this domain. Any experienced SNOW developer who can shed some light on this?

I am planning to switch, so will it be a good idea to switch in servicenow tech only or should I consider any other core development tech?

I currently only have ITSM knowledge in SNOW.
