The obvious answer in an AI world is that the domain expert becomes the valuable employee. If you don't know enough to direct these models with the intelligence, wisdom, and judgement that only being a domain expert can confer, you're not going to get the results out that you need to actually get anything useful done.

So no, they won't need techies, but PhD level biologists are safe. In fact, PhD level biologists leveraging the advanced AIs to come in the future are likely to be exponentially more valuable than entire bio startups are today. So if you're young today, don't be foolish. Don't go to college and get some CS degree with an eye towards getting a job in tech. That's very likely not going to work out for you long term.
