I'm actually starting a real estate tech company, so my perspective having spent most of my career in high tech is this: I don't think technology actually eliminates white collar jobs. Technology is very good at eliminating blue collar jobs, and we've seen this over the past few decades. If there are jobs that can be automated by technology, it most likely will be.
I don't see RE agents as one of those jobs. The parts of a RE agents job that can be automated are already being automated. And the best agents are already taking advantage of those technologies. What tends to happen in white collar careers is that those who are most adept at taking advantage of new technology will distance themselves from those who don't, and there will be a bimodal distribution of talent.
One of my friends who is one of the top producing RE agents in California uses technology extensively, and I'm shocked when he tells me of his competitors that are still using pen and paper to track complex contracts.
At the end of the day technology is nothing but a tool, and those who wield it best have an unfair advantage. This has played out in almost every field of human endeavor since the advent of computers. Much of the "wealth inequality" is a result of technology taking a 10-20% difference in intelligence, competence and skill in any given field and leveraging it to 10-20x.
I've met many successful people in real estate, and by and large the ones who are doing the best are the ones that have embraced technology. The absolute best ones are teaching others to do the same.
