We're near the end of scaling in silicon but we're nowhere near the physical limits of computational efficiency in general. There are certainly hard limits and improvements will have to cease eventually but not necessarily until the later pars of the 21st century.
- tcoppi 10y agoThe trouble is various incarnations of silicon-based transistors are the best we know how to engineer right now and for the foreseeable future. There will probably be a stall for at least 5-10 years after silicon scaling ends in the late 2010s/early 2020s while we try to develop a suitable replacement that can continue to the ultimate physical limits.
