A lifetime is a long time. I have no trouble believing enclosed agriculture is uneconomical now, but look at the trends: robots and AI are set for a long run of improvement, daytime electricity is likely to get much cheaper with the progress in solar power (when prices have been roughly level since 1970), people increasingly want local and fresh food without pesticides, harm to the ecosystem is an increasingly big deal, and so is variability from climate change. A couple of more speculative possibilities: median income might start going up again (it roughly doubled in 1950-1970) and nuclear power could make a comeback with the new startups tackling it, for even more abundant cheap electricity. So how far is the tipping point for some crops, and then most?
