- Don't you think miners have already enough power with their hashrate ...
Yes.
... that if they "win" this game they will be too much powerful...?
No.
Allow me to explain. The miners have exactly as much power as they have (is that a tautology?). The outcome of this will not change the balance of power. The fact of the matter is that in the system that Satoshi designed, the only power that stands against the miners making any changes they so desire is the power of the users to abandon the chain, making it worthless.
...than desirable?
Kind of. Not exactly. I regret that I did not fully understand Satoshi's design back in the early days of ASICs / late days of FPGAs. I -- along with the vast majority of the community -- abdicated my role within the power structure of Bitcoin. All the more regrettable, as I once participated as a (not insignificant) miner. But the simple fact is that we collectively ceded our power to a small collection of specialists.
But just as DiscusFish once had the clout to 51% the network on their own (which, BTW, they chose not to do), this too shall pass. As Bitcoin continues to grow in world monetary scale, it will eventually attract a new class of silicon vendors. Ones that exist already to sell silicon in general terms - not to specialize in the arcane details of the merchant Bitcoin mining business. With their own leading-capability fabs, they will be able to outcompete BitMain's model of outsourcing their fab production. And these high-volume silicon vendors will sell their wares to manufacturing powerhouses, who will in turn sell their mining systems to the populace at large on open terms. And we will all be able to get back into small-scale mining. Harvesting the waste heat to useful ends (residential water heaters being an obvious first target of opportunity?). Collectively outweighing the centralized mining houses. Likely still dependent upon pools, but not captive to the whims of the mining company CEOs.
- From what you have just said, I think you are not against Segwit/LN, are you?
Not really. There are some aspects of The SegWit Omnibus Changeset that I like, others that I think would be better solved in other ways, and others that I dislike. But I'm not against it just for the sake of being against it.
I "think" you are much more invested in Bitcoin than I am,
No idea. Other than pretty much everyone that I know would be downright astonished to learn the value of my Bitcoin holdings. Read into that what you will.
so I supposse whatever you support you do it in your belief that it will be a price boost instead of the oppossite.
Absolutely.
Also you seem to be "tech inclined" so that's why I want to understand your position.
While not particularly literate in Bitcoin tech (i.e., I've not studied to the point where I would be a competent Bitcoin dev, though with study it is certainly not beyond my capabilities), I am indeed tech inclined. My day gig is in a significant tech position with a significant tech company.
Thanks for considering my position on its merits.
