Well I agree that hours don't always equate to value, in many cases they don't for the reasons you pointed out. Ultimately it matters what kind of experience you have and how valuable that is in a given context.

My point was if I had to pick one broad generalization - "value increases as hours increase", "value is independent of hours", "value decreases as hours increase" - it certainly makes sense to pick the first. Extra hours are more likely to make you more valuable than to make you equally or less valuable.

This was what I was replying to

Thats why I do take it for granted (on average) that people who do side projects do better than those who don't. With 2 equal resumes I would confidently pick the one who started programming early. Nothing is certain when generalizing like that obviously, but then again no signal ever in any interview is a guarantee of future work performance.
