AI won't disappear definitely. However, more graduates will enter market as we move forward. Thus there will be more supply than demand which leads to drop in salaries.
This has happened in many markets in recent years. Don't you recall big data hype around 2007? You would be considered as God if you can barely install Hadoop back then.
Competent big data folks still pull down $300-400k fairly easily. I’m talking about people who _really_ understand the field and have a track record, not “graduates with a degree”.
starts at 400k? where do you get that number? I can imagine a director 3 type position, which would be true for most fields. But interviewing, talking with recruiters, and looking at salaries on glass door, facebook pays a median 130k. Amazon pays closer to the 100k side with a maximum of 165k, an absolute ceiling that shall not be passed. There is stock, but even being equal to base, still no where near a starting 400k
