Even some people do not get convinced on hearing about bitcoin for the first time, they will get back to know more about bitcoins if they come across if bitcoin gets into higher prices like $100k or anything similar. So, having this kind of debate is very important.
But the price debate shouldn't be the main motivation for newcomers to get into touch with cryptocurrencies. The financial incentive does play a role, but if they willing to put in the effort and develop a decent understand of cryptocurrencies they are much more likely to turn into real Bitcoin supporters. That's why debates are important, but those talking in favor of Bitcoin need to be good at breaking down complex theory into practical knowledge.
It's only when there is a lot of hysteria in the market that google searches shoot up and many of those interested are rather watching out for a quick buck than about understanding Bitcoin in depth.
