Ask HN: Are we in the new dot-com bubble of crazy IPOs (2021 edition)?

Accordingly to some public data, in 2021 we have enoumeous number of IPOs, including such companies as:

- HashiCorp

- GitLab

- Transferwise (now Wise)

- Reddit

- Udemy

- Duolingo

- Couchbase

- UiPath

- Coinbase

- Coursera

- DigitalOcean

- Roblox

and also > 1000 lesser known companies (or at least, lesser known to engineering community). There were 480 IPOs in 2020, 232 in 2019.

This makes me think: are we about to see the 2000s bubble crash soon or it's different this time?
