That is a good question, but I cannot say for sure yet.
However, the Abstract states;
1
"Existing multi-agent and agent architectures have seen no significant adoption"
meaning current agents are not being utilized by new users, therefore;
2
"The framework bridges the old and new web and employs distributed ledger technologies as core parts of its construction."
meaning that FET could 'bridge' or connect OLD systems, and NEW web systems, using blockchain technology. They have chosen ETHEREUM and ATOM chains, as I highlighted above, where these tokens exist.
In my opinion the difficulty and the cost of using these chains is still a barrier they still must overcome. I hope this was informative, and that you always use caution when exploring new projects.
LEARN all you can first before you make decisions to acquire new tokens.
