So the question is, do you think RISC-V as an open source architecture emerge as real competitor to ARM?
I will certainly be playing with it, and using a RISC-V desktop as soon as it's viable.
Broadly though, what the tech world needs is a democratisation of hardware. We need to move toward reusable, flexible, stable, transparent and more standardised, chips (though not all of these desires are necessarily compatible).
We need simple trustable, auditable microprocessors free from "management engines", user hostile enclaves and pay-per-core shitfuckery. This isn't only about end user choice and privacy et cetera, it's about long-term ecology, sustainability and resilience.
It's no big stretch to imagine Intel announcing an AAE (Advanced Advertising Engine) that steals cycles to insert ads directly into your applications - then millions of discarded products ending up in landfills as people revolt against technology hijacked to be tools of manipulation and domination.
Problem is, VLSI fabrication is a dangerous, expensive and messy business. RISC-V goes some of the way to offering a "peoples' microprocessor", but nobody is going to set up production in their garage any time soon.
Investment in SME boutique fabs would be much nicer than pouring money into Intel. If we are going to bring manufacturing home, I'd like to see services not unlike the old vinyl record business, where a small company or group of hobbyists can buy small-run batches of 100 chips designed by a web interface - drag and drop four RISC-V cores, some cache, a neural processor, some audio DSP... and have it drop into a standard package socket, boot, and be cryptographically verifiable as the intended design with a simple JTAG scan.
I guess we're a long long way from this "silicon Lego", but that's my dream.
But I just read today of silicon wafer shortages, so story goes deeper...
