Is the market's current momentum just an earnings mirage?

I'm genuinely curious about how much of the recent S&P strength is truly organic versus simply a reaction to some strong earnings reports, particularly from the tech giants. It feels like the underlying economic picture, even with inflation cooling a bit, still presents some headwinds. Are we overly reliant on these Q1 numbers, and could a less stellar Q2 really pull the rug out? I'm open to being wrong here, push back on this if you see it differently.
