See, the thing is that most people think research or gaining knowledge – whatever you want to call it - is something linear, while in reality it grows exponential.
Let me explain a bit. Imagine we would have started in the year 2000 with zero knowledge but possessed the research rate we had in this year. By the end of the year 2010 we would have already researched everything we have researched in all the millennia before. 
Try to understand that for a moment, since it's really hard to gasp and understand exponential growth or exponential functions for humans in real life. Humans are more of a Newtonian physics linear type of being.
Gaining Immortality in this context is just one more step for a scientist to archive and in the long run just remembered as an important point for humanity, like the pyramid, the first flight or the first a-bomb. However, this guy is not telling the truth or wants to lie, because we already accessed this technology like 8 or 9 years ago. Want to live a 100a more and look like in your 20s? No big deal, just give me 400-500 M€ and it's done.

Duh, that's the Fermi Paradox solution: once a species becomes technological it is already effectively extinct on geological timescales.
All species evolved in perfect opposition to their environment. This happened in (and still happens in) a relatively linear progression. Meanwhile, technology is the means to augment the environment.
Augment it how? Towards those desires and away from those inhibitions which were evolved-in of course!
The net result: an environment changing towards the subjective 'better' at an exponential rate which the linearly-changing evolutionary growth can never hope to match.
This is visible in everything from the lack of exercise in obtaining food leading to obesity and the lack of fasting leading to buildups of toxins in the body all the way through modern liberalism eroding the family structures adhered to for millennia and birth control plus contraceptives allowing, get this, women voting - creatures which were the literal trophies of war for all of Human history and have no natural inclinations whatsoever to make the right choice in any regard (if the wrong choice was made they just got fucked by and reproduced with someone different, they didn't get eliminated with their genes purged like men did each and every time they fucked up,) just to accept their environments and manipulate psychologically to stay alive.
You best believe in the techno-Fermi-paradox, you're living it.
