And pigs might fly
Apple couldn't justify the R&D expense in trying to compete with AMD, NVidia or Intel in the high performance GPU or CPU market.
There's very few 'professionals' left on Mac OSX, most have moved to either Linux or Windows. Thus why Apple didn't refresh their Mac Pro for how many years, was it 5?. Sell 'pro' laptops that are so thermally limited it's pointless paring them with mobile i7s or i9s, and made Mac Pros like the Rubbish Can. So too why they don't offer 24/7 or next business day on site warranties on their computers like Dell or HP. Because their core market for their computers for nigh on a decade has been consumers who use their devices for nothing more than home/office productivity.
This isn't the 1980s or Mid 00s anymore, the market that cares about high end or powered Macs is so small Apple don't even care for them and haven't for years.
