What is special about implementing anything Bitcoin+Lightning? BAT clones are already being developed on EOS and IOTA (both speedy networks with 0 cost transactions). Here's the IOTA advertising project: https://oysterprotocol.com/
This is a really strange claim, from the perspective of someone not invested in any specific implementation of crypto or blockchains...why would the first product in a given (tech) category be the one that lasts the longest? That would be like expecting WebCrawler to be the dominant search engine or Six Degrees to be the dominant online social media site, or Mosaic to be the browser with the highest usage %. I can't figure out why someone would make this argument unless they have a personal interest in keeping Bitcoin's value high.
Basically you think Bitcoin cannot ever be "the one that lasts the longest" just because it was the first implementation? That's a valid argument, but it makes no sense to think that all other arguments that claim the contrary are invalid and can only be made by people with evil intentions of enriching themselves.
I mean, you just made the claim without any sort of support besides saying that BTC + Lightning alone will "truly function as money" and, absent any arguments, it's much easier to imagine the opposite.
I think it's reasonable to think that people that just say "bitcoin good altcoin bad" without really saying anything else aren't making good faith contributions to discussion and may have other motives.
Both of the projects mentioned are in the top 10 of crypto projects and have billions in their marketcap, why don't you think they'll exist in the future? Over 100 engineers and scientists work at the IOTA foundation, and EOS probably has similar numbers.
Well, much more than 100 engineers once worked at a lot of companies that vanished soon after. There are lots of arguments on why Bitcoin will last and not the others (and vice-versa) and I can't cite them all here, but the most important one is: in the end, there can only be one money.
