Give it some time - just like LLMs the first VR headsets were created in the 90s (for example by Nintendo). But it took another 30 years for the hardware to achieve levels of functionality and comfortableness that make it a viable consumer product. Apple Vision is starting to get there. And crypto is even younger - it started in early 2009. For people living in countries without a proper banking infrastructure the stablecoins are already very helpful. Billions of people live in countries that don't have a well audited financial sector, that respects the rule of law or an independent central bank that makes sound monetary decisions irrespective of the government. For them stablecoins and their cheap transactions are huge.
