I'm betting I could find articles arguing against being in a bubble (like @sama’s) from each of those years as well. There will likely be a deflationary period in tech in the next decade, worse than the small recession we witnessed at the transition between 2015-2016. But I don't think tech is so separate from other market sectors anymore, so it won't (IMO) be a tech-specific thing, just a normal market cycle.
