I will not be providing proof here, but I went from someone who last wrote production code >15 years ago, to last week, a Fortune 50 demo client saying "this is far better than our internal tool." I am a solo builder.
I am thrilled to report that after 1.5yrs of rice and beans: yes!
The first client has paid, and signed a 3 year contract. Not huge money, but 5 figures per year. That client didn't even see what the F50 demo user saw.
I feel like I am an outlier, but I do exist.
