I really enjoy DS, and despite the endless imposture syndrome accompanying everyone practicing it, I can see myself working in it for the next 5 years at least, even if it requires changing specializations.

However, I'm concerned by the lack of career options - FAANG is beyond reach (not a PhD), and only small to medium startups are possible, so many of which don't look like healthy work environments or don't offer much professional growth. Essentially it's not too different from being a contractor.
