Also there is clearly no interest in improving bitcoin within the community. Because the process with which bitcoin upgrades itself is so slow, cumbersome and uncompetetive, bitcoiners have this cognitive dissonance that causes them to claim that bitcoin is already perfect and should not be improved further.
It isn't bitcoin's role to provide advanced functionality - at least not as far as its valuation is concerned.
They could leave it just as it is for a couple of decades and it would still accrue in value because its role (increasingly) is to act as the reserve reference for the entire crypto currency economy. It doesn't need to do anything fancy, it just needs to exist, exhibit rock solid blockchain security and be reasonably accessible.
A 20-30 minute block time is just fine in this regard. Meanwhile, the rest of the alt coin world can get on with providing the singing and dancing wherever it's needed in specialised sectors such as Point of Sale, ultra-anonymity, equity management and decentralised exchanges.
As long as everything else continues to be priced in the BTC reserve, developments in alts will continue to attract capital to bitcoin itself without it having to justify its existence in terms of technological bells and whistles. Bitcoin isn't in competition with alts anymore - it's value is a proxy for the entire cryptocurrency economy the same way as the dollar reserve represented the entire western economy under the Bretton Woods system.
(P.S. Similarly, gold didn't loose its value when Visa and Amex were born. It just sat in vaults doing its "thang").
