We are in crypto where the internet was in the early 1990s. Way before the dotcom bubble. Even though crypto has seen bubbles, it just comes down to the nature of coins which are only tradable, while internet itself was not tradable before big companies appeared in the stock market.
We need at least 5 years before seeing some maturity. We also need technological advancements with regards to scaling (especially on the hardware side in my opinion).
Messageboards and images that take 2 minutes to load? :D
Yes for sure, speculation on projects is quite meaningless in my opinion.
Yep, I think that there are massive scalability issues coming, but at the same time, they aren't likely to get really considered until there are more participants. Nothing drives innovation like missed profits :)
