One hopes that ‘fusion’ is not going to become an expression like 'ecosystem', ‘solution’, ‘disruptive’, 'platform', ‘embedded’ and ‘paradigm shift’ which have been over-used beyond the point of meaninglessness.
Samsung has just come up with a chip which transfers data between processors which it calls, ‘powerhouse fusion memory solution’ a four-word phrase in which three words are redundant.
Last month Gillette came up with a disposable razor with loads of blades which it called ‘Fusion’. Ford uses it as the brand name for a car, and it is also used to describe cooking.
Fusion used to mean the creation of nuclear energy by fusing atoms at very high temperatures as at Culham in Oxfordshire, and as was the subject of the agreement, earlier this month, between the US, EU, China, India, Korea and Japan to build a fusion plant in Cadarache, France.
When used in other contexts it sounds a bit pathetic.
