If you are talking about the impact of crypto world to the global industry if Satoshi Nakamoto is alive and comes out to the public then I would say that it would not have much of an impact since other industries have their focuses and goals to reach. Satoshi Nakamoto is neither related to these industries' important matters to attend to.  But if we are talking about the impact of Satoshi Nakamoto going public to the cryptocurrency industry then I can say that the sudden appearance of the creator of Bitcoin will temporarily boost the market.  We might experience a sudden spike in the Bitcoin price which might last for some time until the market is getting used to Satoshi's presence.  The usual law of diminishing return.

There might be lots of huge events that involve Satoshi Nakamoto and probably he will be invited to the mass media for a forum or interview.  By this time, the spread of Bitcoin information will leap to a new height and the pro-Bitcoin government might invite Satoshi for a conference.

Anyway, all these changes are temporary since the market will eventually goe back to its normal move, so we might expect a huge correction after the huge hype created by the appearance of Satoshi Nakamoto.
