The hype-to-reality gap is going to keep getting much bigger every generation of announcements due to Dennard scaling and the end of Moore's Law. I was fortunate enough to be an active computer technologist through the "golden age" from 1980 to ~2010. Every three to four years things got about twice as fast for around half the cost. And not just some features or aspects but almost the entire system in almost every way. We had no idea back then just how extraordinary that period was.

Today, the industry has regressed to hyping tiny incremental gains in narrow sub-metrics which only rarely have a material impact on overall performance across an entire system or most applications and usually at higher cost. Those that entered the industry in the last 15 years don't really appreciate just how much progress has slowed to a crawl.

Sadly, looking at the ten year roadmap projections from the likes of IMEC, there aren't any big leaps on the horizon. Progress will come mostly in single-digit percentages and most gains will be increasingly conditional (eg limited to one logic type or only in certain contexts). And the costs are going to keep skyrocketing. I hope we'll "get lucky" with some unexpected breakthrough but there's no reason to expect that.
