Can somebody ELI5 this to a normal tech person who is aware of the RISC5, but has no idea why everyone is so excited about this?

• Why is this exciting?
• Is there a future where this replaces x86 CPUs in the desktop / laptop?
• Will emulation or translation layers allow x86 applications to run on RISC CPUs?

Self hosting is much closer to gaming on Linux than Windows imo, but it’s a great analogy nevertheless.
