Which CS research areas offer the best combination of career longevity, income, and impact?
I am planning to apply to CS PhD programs and am considering which research areas to pursue. I want to identify areas that:
- lead to lucrative job opportunities in the short, medium, and long term;
- offer substantial entrepreneurial opportunities, preferably without requiring large amounts of upfront capital;
- are likely to remain active research areas for many years; and
- provide opportunities to make a significant impact.
I am researching publication, hiring, funding, and investment trends, but individual researchers may have insights that are not apparent from publicly available data. Which areas currently offer the strongest combination of income potential, entrepreneurial opportunity, research longevity, and impact?
Conversely, which areas may appear hot but are already producing diminishing marginal returns or becoming crowded? (LLMs?)
I understand that money should not be the sole reason to pursue a PhD or choose a research area. However, financial outcomes are a legitimate consideration. There is no particular virtue in becoming a starving scholar when it may be possible to do meaningful research and also become financially successful.
I also recognize that research direction often develops during the PhD rather than being fixed before admission. Still, I would like to make an informed choice about which areas to explore from the outset.
I am grateful for your feedback.
