I can't tell whether you're trying to make an argument with this comment or what's the reason for pointing that out.

The point is peak oil as a concept has existed for a long time, and we have extended way past its deadline before. It relies on not having technological advancement for accessing more oil.

Not exactly: it relies on future sources of oil (unconventional oil) having lower EROI (Energy return on investment) than historical oil reserves (conventional oil). Technological advancements could conceivably increase the EROI of some unconventional sources, but they mainly seem to make new lower EROI sources available.

Sure but that's not really argument for anything, it's just hopium. Oil is a finite resource, it will run out. Just because some breakthrough shift the timelines doesn't mean that the analysis isn't sound. There's no guarantee that another breakthrough is always coming.
