Jack Dorsey is a staunch evangelist for Bitcoin. BTC indeed has a chance of failing, although it's a low probability. Most people only see the current price and then determine how the future will be, just like the countless believers in ETH who once were OGs.
He calls for the development of simple and secure payment solutions. This is not a potential reason for BTC's failure; BTC is only suitable for large transaction solutions, while high-frequency small amounts can use Dogecoin. The Lightning Network and other solutions for BTC have not seen success either.
In my opinion, the biggest risk of BTC's failure in the future comes from the centralized control of Wall Street, stemming from the abandonment of the underlying technology. Those who stand high and mighty think they have enough chips to control everything; what they fail to understand is that when that day comes, perhaps no one will want to play with you, just like retail investors today don't engage with the altcoins dominated by VC institutions, preferring to participate in MEME gambling.
In ten or twenty years, BTC will follow the stock market, fading into mediocrity. For the next generation, BTC will just be a purely financial investment or storage tool, losing its charm, losing its appeal, losing its spirit of innovation, lacking passion and excitement, and no longer having the consensus and support of the vast grassroots population...
What goes too far must come back; I don't know when another great tech geek will rise up, and with a call to arms, thousands of individuals abandoned by BTC, grassroots communities, rooted in stronger technological solutions, will recreate a brand new BTC.
The value of BTC comes from the consensus of the majority. Once it becomes a tool for the minority, it will be nothing more than a pile of worthless code. When the majority gathers a new consensus, a new BTC will rise. It's just not the right time yet.
