If one were to take the Google vs Blackberry comparison, then Blackberry at $100 was already an established player with majority in market share of that sector. That's basically what one could take for GM, Toyota or other major auto company that holds a major stake of the auto business. A disruptive technology can grow VERY FAST if it's a revolutionary product, not an evolutionary product (iPhone 1 was revolutionary, iPhone 3G was evolutionary etc). Therefore a trenched in established player with majority stake in the industry has everything to lose unless they continue to innovate and outpace competition. Blackberry didn't do that and ended up in the single digits.
Tesla is more like Google in your comparison. A proprietary ranking algorithm that works better than any of the competition with growing ad revenues, but still a relatively minor share of the market. Or even better example would be Apple at around the time they introduced iPhone 3G. So they had a revolutionary year with seriously limited distribution of iPhone behind them (remember, the original iPhone was only sold in US even though everyone and their cousin unlocked and shipped worldwide, including to me), had proved the business case and how they differentiated from everyone and all the major competitors still laughed at the product, but were slowly starting to think about it. Apple at the time had already grown beyond just the Mac business and was trading at around $100. Now even with the major recession hitting a year later Apple went to $700 in 5 years time and now has settled between 500-600 having basically conquered the markets high margin business.
The difference in Apple comparison is the timescale of a product cycle. For Apple and competitors the cycle is 1-2 years to go from nothing to a product that is hitting the market in millions. Therefore the moat Apple had only lasted a few years until Android based phones started to catch up. Yet they still command majority of the profit. For car companies the cycle length is more likely 5-7 years from nothing to a product that is selling and even longer to get it selling millions of units. Therefore we need to expand the Apple timeframe of 5 years by a factor of 5 or so. This means that Apple hitting 7x the original price in 5 years could be translated to TSLA hitting 7x the current price in ca 25 years. So predicting the cycle out to 10 years and considering that TSLA is even earlier in the curve (we should probably look at iPod introduction, not iPhone), the multiplication in 10 years could easily be 3-4x or we could be semi-flat due to some recession in the middle.
And as an aside, I can predict my employment future out multiple decades unless I decide to shake things up myself. Researcher careers are relatively stable and I've only just gotten the position of senior researcher (at the age of 32) that basically guarantees employment for the next 20+ years

I could probably live as a researcher in HEP until I retire or kick the bucket (which ever comes first), but I might shake up things and start something instead in that 10 year time. Still, it's not that hard to predict. And 10 years ago I had just started working in research and could easily predict that in 10 years I'd be still in research except maybe a researcher or senior researcher (the latter with lower probability, but a bull case).
