OP, they can be a threat but that is not happening. Miners know that the community has the power to do a user activated hard fork to "brick" their Asics.
This brings back me to Cobra's blog. Everyone should read it whether you agree or disagree.

trying to be unbiased. cobra's opinion is flawed in many ways.
1. by separating mining from the nodes(2013) actually splits the point of failure. because instead of core changing something and the whole community moving. the pools have to agree/disagree. this made core (in 2016) not fully tyranical because core cant control the mining internally via code. this is why core did not get segwit activated in december 2016 because they only had ~30% of the community vote.
2. as my previous post said pools cant simply change the rules and mess with bitcoin. because the nodes/community have to agree. but nodes too shouldnt have the power to change the rules without the pools or node users agreeing. which core abused by making opposition/abstainers shift to a altcoin to unanimously get their fudged 95% in 2017
3. this is where we do actually need multiple full nodes made by different teams, which can use consensus to make agreements on positive changes. and not allow negative changes, rather than just 1 team acting like tyrants avoiding consensus by throwing opposition into altcoins so they always win the vote.
anyway the other major flaw of cobra's thinking is this:
4. if a mining algo change did occur. in a fair and multi team consensus agreement... it would still not help the little guys get on the profit ladder.. big mining companies (yes there are many more than just bitmain, although cobra wont admit that) these mining companies will just pool together many nodes and within a short time be back at the top of the ladder again.
EG
if it was a PoS.. lets say 100k individuals staked. .. 20 pools could simply make 10k stake each(200k) 3.3% of the time a pool get a block and 0.00033% of the time a individual wins a block
EG
if it was a PoH(harddrive).. lets say 100k individuals had nodes. .. 20 pools could simply buy 10k raspberry Pi's each(200k) 3.3% of the time a pool get a block and 0.00033% of the time a individual wins a block
so no matter what within hours/days weeks. there will always be a way to 'pool' resources
to me i am not worried about pools. as my previous post pointed out. the real point of failure is the lack of diversity in node teams
