alt Hacker NewsAre you seriously suggesting hobbyists should tapeout an ASIC instead of use an FPGA?
1. For one-off designs (quantity=1) ASICs will never beat a high end FPGA on unit price.
2. As a hobbyist, you want to EXPERIMENT. You cannot do that with an ASIC. Hobbyists want to do something simple, test it on real hardware, and slowly build up from that. I don't have the time nor expertise nor motivation to spend months writing verification to get it right the first time for a tapeout.
"Just use a microcontroller"... I will concede that microcontrollers do cover 90% of hobbyists use cases (that number increasing by the day). But for hobbyists sometimes you want to learn HDL or digital logic or computer engineering. You can do this hands on with a FPGA much more effectively than in software.

They already need to maintain the Linux build for all the other paid tiers?? These are the same software with different features locked behind a license key. It costs them NOTHING to keep the build enabled for free tier.

No. I said the low-end of FPGA sales is getting eaten by microcontrollers and the high-end of FPGAs sales is probably about to get eaten by custom ASICs.
Although the cost of making an ASIC is high, in the larger nodes it's not that high, and getting ever cheaper at FPGA performance levels and logic densities. FPGAs are terribly inefficient with their HW they're very easy to beat with an ASIC. They only get away with it because the NRE today is lower. But it's not an order of magnitude lower and I'm not sure how much longer that will be the case in nodes at 28nm and larger based on what I know Universities pay in tape-out classes.
Will there be very low qty projects where the NRE of developing an ASIC overwhelms that of an ASIC, sure. But will there be enough business in that niche to sustain the business of AMD, Intel and Lattice? Not obvious.
And I don't think the FPGA hobbyist market of people who "want to learn HDL" spends enough money to affect what's coming and this decision from AMD reflects that.

Never say never. These guys were able to convince investors you're wrong about that. :)
