If he doesn't want to actually learn AI/ML itself, there's an endless number of adjacent jobs related to all the hype:

* web dev - today the majority of the jobs are very heavily ts/js, react, next.js, vercel, etc.

* data engineering - AI/ML is very hungry for clean, organized, and accessible data. so we're talking sql, data warehousing, spark, beam, kafka

* infra/devops - nearly every tech company needs these people: docker, kubernetes, terraform, ci/cd, gitops, metrics and monitoring tools like prometheus and grafana
