I think to some degree the quality on the whole is likely to diminish over time, this is simply the way that technology works. The elite level specialists usually get their hands on it first, then it trickles down to those who are technically proficient, before then being accessed by the standard person, and finally then accessed by the technologically illiterate.
That being said, there is still a new wave of people who take the time to learn, and eventually build themselves up to be masters in the industry, these didactic individuals are present in nigh every industry and ensure that the flow of new talent is always consistent, as there are always new generations of people looking to involve themselves in tech. I also think that public resources on bitcoin and supporting technologies is becoming much more widespread, this allows those with the desire to easily educate themselves in things like Blockchain, Solidity, Node.JS and other core languages to keep generating a steady stream of pioneers.
Hopefully this trend continues, it is true that most of the game changers have been early adopters, e.g. Vitalik Buterin, Zooko Wilcox etc, but there have definitely been some promising ICOs lately that don't appear to have been started by the first movers, e.g. NEO and ADA, but regardless usually have some oversight from early advisers. I guess that's the nature of all games, you either get in first and become a whale, or scrape your way to the top as the climb becomes more congested.
Never stop learning people. You might become the next Satoshi.
