Do more research. Is this even nonpublic knowledge at all? The world economy grows at something like 2% a year, labor costs generally seem to go up, prices of computers and robotics usually falls... Do industry projections expect to grow their sales by <25% a year?

If so, I might spend some of my hypothetical money on whatever the best approximation to a robotics index fund I can find, as the best of a bunch of bad choices. (Checking a few random entries in Wikipedia, maybe a fifth of the companies are publicly traded, so... that will be a pretty small index.) But I wouldn't be really surprised if in 10 years, I had not outperformed the general market.
