It is anybody's guess what the future will bring, but on past form GPU programming will remain a niche for specific highly-tuned (HPC) applications and mere mortals can focus on somewhat easier multi-core CPU programming instead. The main reason GPU gets so much attention these days is that CPU manufacturers (Intel in particular) simply cannot get their act together. Intel had promised significant breakthroughs with Xeon Phi like a decade ago. In the meantime people have invented more and more applications that need significant computational power. But it will eventually get there. E.g., AMD' latest epyc features 96 cores. Importantly, that computational power is available in principle with simpler / more familiar programming models.
