He is very offensive, but what really makes me sad is that I sort of agree with him. I think that the opportunity window for Monero's success probably closed many months ago. (If not, there is very little time left). Great technology, but there is NO Marketing, and no (Non-Techno-Geek) user friendliness. Nor does there seem to be any recognition that these factors might be important.
Beta was superior to VHS. But that analogy is flawed, because those two videotapes were functionally more or less equivalent in their applications. But the Market obviously sees the potential functionality of ETH as superior to that of Monero. And again, there's a disparity in Marketing among the two. Look at their ages, and their market caps. And ETH is not yet finished either.
The "NO Marketing" is intentional, because of the "no user friendliness" you also note.
Monero isn't even out of beta yet. We can't really judge its success or failure until after multisig, confidential tx, and the GUI (not to mention some marketing) have given the coin a chance to gain market share.
