I think the point they're making is that Bitcoin has 5.5 years of development, we have a couple of months. It "feels like Bitcoin in 2010" because it's the wild west, rough and raw and unknown and hard to use. I'd hope that in the next 3 or 4 or 5 years the Monero landscape will be vastly different;)
I know what the point is, but it applies to every other altcoin. So singling out Monero makes no sense. I could single out twenty promising alts, and use the same line of argument. There is no solid reason to believe Monero will become another Bitcoin. Just because it's possible is not sufficient as an argument. It is possible that Beertokens will get a new dev, and take the coin to the moon. It is possible that there is no external world, and we are just brains in VATS (google it). There are infinite possibilities, and Monero does not appear to be placed in a position where we could say the possibility was a probability.
probability is dependent on point of view..
calling the "next bitcoin" is basically enthusiastic and no serious investor will invest based on such statements. crypto note has great potential especially compared to generic clones, which most of alt coins are.
Probability is not based on point of view. Some things are improbable, so we can't go down the road of calling the improbable probable.
Probability is a term used when there is evidence from normally reliable sources to suggest X will occur. In fact, probability is all we really have. Tomorrow, the sun will probably rise.
Don't lump fantasy together with probability.
