Billionaire entrepreneur Elon Musk, co-founder of Paypal, and electric car company Tesla Motors took part in a panel discussion with the Taoiseach Enda Kenny this evening at the Web Summit at the RDS.
The superstar of the tech world flew into Dublin shortly before the summit, and brought with him a green Tesla car - the first electric vehicle to be acclaimed by motoring critics.
Named in Time Magazine's 100 Most Influential People, Mr Musk is also the founder of Space X which develops and manufactures space launch technology.
Addressing the packed halll, he gave some advice about how Ireland can tap into the expanding technology industries. "The most important thing for creating companies is that you need a concentration of talent, you really want to focus your talent on a particular area," he said.
And he also told Mr Kenny that there should be regulatory and government taxation supports in place for fledgling companies. "And they should be there for companies from start-up to the medium phase, because where companies tend not to make it is at that intermediate stage," he said. "When a new company is formed and you're going up against established companies and you're trying to build some kind of credibility, it's incredibly important that companies are nurtured through that phase - it's like a little sapling growing in a redwood forest, you need that little bit of sunlight".
The Taoiseach - who had been driven to the side of the RDS stage by the Tesla boss - described the car as "extraordinary", and pointed out that Henry Ford had started off his motor company in Cork - "so if you're looking for a good base, we'll give you a fair hearing and our workers will not let you down," he told Mr Musk.
The panel discussion, which closed the hugely successful two-day convention, was chaired by Storyful founder Mark Little.
