To me it seems like there have been talks about BTC becoming scalable for many years now. BTC is decentralized and secure no doubt, but if we don't solve scalability, how can this ever work out? And if BTC doesn't solve the trifecta, perhaps an altcoin will; before bitcoin does.

I know Blockstream has made some interesting products, by Adam Back (most suspicious person for being Satoshi). But these are all products that are not running on the Bitcoin main network (not decentralized, secure is arguable).

It's my main fear for BTC not succeeding, never becoming scalable. The halvings have been cool in pushing us into new bullruns, but this 4th halving will be a minor decrease in mining rewards compared to the previous ones. Sure we can have other bullish catalysts, but I don't think it will cut it. We've had some of the most bullish (in theory) moments in time for BTC these recent years, but we couldn't latch on; because frankly, Bitcoin is not finished yet. If it could scale on a massive global scale like advertised - It would have been mass adopted during the pandemic and hyper inflation times.

Am I naïve, is there any reasonable chance for BTC to conquer its scalability issue? It's amazing the Byzantine General's problem got solved, but now we've got a 'trifecta' problem. A cryptocurrency can't be decentralized, scalable and secure all at the same time.
