Profile: 25 years old, targeting retirement around 55-60, so roughly 30-35 years of runway. Currently planning to go 100% VWCE and just hold.

Three things I'm trying to figure out:
1. Is 100% VWCE actually optimal for this time horizon? I know the standard passive advice is just buy a global ETF and forget it. But with 30+ years I can theoretically absorb more volatility. Am I being too conservative sticking to just VWCE, or does the diversification actually make it the right call long-term?
2. Does the AI/tech boom justify a tilt? VWCE is already ~65% US and heavy in tech. But given the sustained outperformance of tech over the last decade, does adding something like QQQ or a sector ETF on top actually improve expected returns, or is it just chasing recent performance?
3. What's the highest expected-return strategy for someone in my situation? Not looking to day trade or pick stocks. Open to small-cap tilt, factor investing, slight leverage (e.g. 2x ETFs), or just sticking with broad market. what would you do ?

Also as an European; how much do you manage to put into your investement each month ? (and how old are you)

Curious how people think about ETF strategy for very long time horizons (30-35 years).

A few things I keep going back and forth on:

1. Does broad diversification beat concentration over a 30+ year runway? The standard passive case for something like VWCE is hard to argue with. But if you have enough time to ride out volatility, does a more concentrated approach (heavy US, heavy tech) actually have higher expected returns historically, or does VWCE's diversification win out?

2. Does the AI/tech boom justify a tilt, or is it just performance chasing? VWCE is already ~65% US and tech-heavy. Adding QQQ or a sector ETF on top means doubling down on what's already the biggest weight. Is there a real thesis for doing that, or is it just recency bias?

3. Factor investing vs. simple market cap: what does the evidence say? Small-cap tilt, value tilt, slight leverage (e.g. 2x ETFs), for a horizon this long, is there a factor-based approach that has stronger theoretical backing than just holding market cap?

Not asking anyone to review a specific portfolio, just interested in how people reason through these tradeoffs.
