Interesting opinion. What makes you believe this? Is it purely based on your comment that you "failed to find consistently profitable quants"?
It's my education in statistics and the theory of information that makes me to believe that, not only the fact that I didn't find quants whose words I can believe. I'm a developer of a Forex simulation product, you can imagine how deep I went into the data to make it work.
Technically speaking, all people who are trying to develop automated strategies use a set of the same small data files, several Mb in size each. We all know all possible algorithms that may work here, there is no secret formula. All these algorithms are based on indicators traders place on their charts, that's what makes them work, not some magic. You see big and complex charts filled with bars, lines, curves and marks which are built from really small static data files. GIGO (Garbage In - Garbage Out).
So, from a mathematician/engineering point of view, there is a relatively simple and short noizy signal and a set of formulas you can apply to it to extract some meaningful pieces of information nobody else noticed before. If you think about it deeper, you will understand my skepticism. It may be fun to believe that you are The Chosen One, but I'm 38 years old to stop playing this game.
I know that it was possible in the past. I found a guy who made $2,000,000+ out of $20,000 in 2001, using quantitative strategies alone based on trader groups' psychological profiles. I also know that all he did in the past can't be repeated at the moment because the competition is much higher in the quant universe. Where he made $20, you will make $0.002 nowadays. He was one of the first, now there are tens of thousands of software developers analyzing the same small data set again and again in various combinations.
Even if you give me some proof that somebody actually made money using quantitative approach right now, will you bet on him in the future? It's a fun game, but I don't want to be a part of it.
You may get more luck building strategies using some exotic data sets, like satellite imagery of parking lots, but how long will it take until everybody else notice this inefficiency? If we are talking about long-term perspective, human+AI will always win against any AI, no matter how complex it may be.
If you are a strong believer in quantitative trading, you should be happy about my decision. Less competition is always better, isn't it?
