I suspect rather strongly that premodern people, too, experienced the physical world more acutely than I do, simply because my brain has been stewing in dopamine-spiking stimuli for four decades now, rarely pausing to touch the proverbial grass. Don’t get me wrong: I like the outdoors a lot. But my waking existence is spent mostly indoors in highly artificial spaces, whereas humans have typically spent the vast majority of their time outdoors in nature. Consider my ancestors, who, as best I can tell, were primarily illiterate peasants and smallhold farmers. They spent a significant proportion of their waking hours literally touching grass.

因此，更应该关注的是博士扩招问题。2020年，教育部、国家发展改革委、财政部等三部委发布《关于加快新时代研究生教育改革发展的意见》提出，“合理扩大人才培养规模。坚持供给与需求相匹配、数量与质量相统一，保持与经济社会发展相适应、与培养能力相匹配的研究生教育发展节奏，博士研究生招生规模适度超前布局，硕士研究生招生规模稳步扩大。招生规模统筹考虑国家需求、地区差异、培养条件、培养质量等因素，实行动态调整，差异化配置”。博士研究生招生规模适度超前布局没有问题，但不能演变为快速扩招。当前，很多985高校都有扩大博士教育规模的诉求，还有一批本科院校想申请博士点，以有无博士点、有多少博士点来评价学校办学层次与水平，为此，扩大博士招生规模没有任何阻力，而且，扩大博士招生规模，还有缓解硕士毕业生就业难的考量。然而，扩大博士招生规模，必须以保障培养质量为前提，如果不能保障培养质量，就必然会导致学历通胀，博士教育注水，博士贬值，也加剧我国社会已经存在的学历高消费问题。
