There was a fierce debate that lead to a hard fork over increasing transaction throughput by raising the block size, so I think it's really not a given that BTC will change to increase transaction speed.
Also, one problem people have with Bitcoin is that the idea of every node of the network storing and processing every transaction is fundamentally not scalabe. Sure BTC can change and adapt, but it's hard to overcome a fundamental design shortcoming.
When there is incentive (if there ever is) then miners will adopt changes that make sense. But you need a true consensus. This built in conservatism is a great feature of BTC.
Increasing block size is simply a bad idea. You do not move fast and break things in mission-critical code. Bitcoin is more focused on working (as it does) and remaining secure. Bitcoin is the best money the world has EVER seen, and it's not important to be able to buy frivolous things with Bitcoin. What is important is making sure value transfer is safe and secure. Those of us who routinely truly use Bitcoin understand we can easily send $50-100 or whichever value you prefer and put in low fees around $0.50-2 and just wait on the money to securely transfer. Not many of us using Bitcoin care if that takes 1-24 hours. The currency aspect is very beta yet, and may even take a few more years to mature and will have to come in layer 2.
The last time this happened we got Bitcoin Cash.
It’s weird to see so many opinions on this website that think BTC is a static thing that can’t or won’t adopt useful pull requests that miners agree are useful.
It’s like if it were the mid-90’s and everyone was just as skeptical of e-commerce of the web in general.
Useful things get better.
