Back in 2014-2015, there was a trend to fork Bitcoin and create a coin pertaining to meme's and etc. This was a big thing, and this is when coins like DogeCoin, EarthCoin and every imaginable Xcoin appeared on Bitcointalk. From BBQCoin, FoodCoin, WaterCoin, Titscoin and etc. This was the trend!
Now, 3-4 years later, we are in the period of ERC-20 tokens, very similar to those coins back then. Now tokens, are getting more serious and are trying to capture industries and rework them entirely. These are basically the majority, a token that functions in a larger system.
Could something else come and replace ERC-20 token standard? Probably, but it's hard to realize and understand what this can be at this moment. Personally, i suspect that ERC-20 token is a very basic concept and more advanced blockchain years down the line will make ERC-20 tokens look like the forks in 2014-2015. When it does happen, it will revolutionize crypto's, just how Ethereum did. Basically, the next big blockchain that revolutionizes the current ERC-20 token trend, will be a top 3-5 crypto. Some new blockchains have serious potential in regards to this, but there isn't anything revolutionary (easy to use essentially) to overthrow ERC-20 yet. ERC20 will be around forever, just like all Bitcoin POW coins, and Peercoin's POS coins.
All technology is an advancement and a step up from another. The next major milestones, i think, will eventually be done by large fortune 500 companies like Intel and etc. The most talented developers in Crypto will get recruited by these companies.
On a side note: Qora was the first crypto that attempted smart-contracts (one could say NXT though). Qora was the ethereum before ethereum imo, sadly it never took off because of development and technical problems.

My weakest understanding is with technical aspects of blockchain and how they are fundamentally designed. I can't go into details, perhaps someone will comment on my remarks here that knows a bit more about what's occurring with the more advanced blockchains.
